The basic definition for a linear servo motor is an automatic device that uses an error-correction routine to correct the motion of the linear servo motor. The general term servo can be applied to systems other than a linear servo motor that use a feedback mechanism such as an encoder or other feedback device to control the motion parameters. Typically when the term servo is used it applies to a 'linear actuator motor' but this term is also used as a general control term with the meaning of a feedback loop to position whatever the item is including a linear actuator motor.

A linear actuator motor is different from other controlled motors in that it is controlled by a time-based derivative commonly referred to as the PID loop. A linear actuator motor that is used to control position must be capable of changing the velocity of the output shaft because the time-based derivative, or the rate of change of position, is velocity.

There are two main types of linear servo motors - Rotary and Linear.

Rotary Servo Motor
A rotary Servo Motor is what most people think of when they think of a Servo Motor. The three types of Servo Motors are: AC Servo Motor, Brush DC Servo Motor, and Brushless DC Servo Motor. The motion of a rotary Servo Motor is often converted into linear motion by the use of a screw thread (ball screw or leadscrew), or with the use of belts and pulleys.

Rotary AC Servo Motor is an AC type motor that is used with a feedback device. These are typically only used in smaller application because a large AC Servo Motor is typically too inefficient when compared to its DC or Brushless counterparts.

A linear servo motor is a flattened out linear actuator motor where the rotor is on the inside, and the coils are on the outside of a moveable u-channel. Both linear actuator motor types are becoming more popular as linear actuator motor prices continue to come down.

A linear servo motor is considered one of the more expensive motors when compared to AC, Brushless, DC, Stepper, and other motor types. The reason for the expense of a linear servo motor is the precision required to make a linear actuator motor and the expensive components that go along with a linear actuator motor. Generally speaking a linear actuator motor is intended to be a very precise positioning or speed control device. The motion should be smooth and very precise. To accomplish these features, the linear actuator motor is manufactured under very tight control parameters. Along with the cost of the linear actuator motor are the case, bearings, connectors, and feedback devices. The case is usually industrial grade, often sealed to achieve an IP65 rating or better. The bearings are high quality to make sure that the linear actuator motor can run the speeds desired and can handle the appropriate axial and radial loads. The connectors are typically mil-style connectors that can be detached at the linear actuator motor, but are very reliable and industrial grade. The Feedback devices are typically differential encoders and or resolvers. The devices are very expensive and add cost to the linear actuator motor.

There are two options for linear servo motor feedback controls, either a servo encoder or a servo resolver. A servo encoder and a servo resolver provide the same solution in many applications, but are vastly different. They are both used to sense speed, direction, and position of the linear servo motor output shaft.

The resolver on the linear actuator motor uses a second set of rotor and stator coils called the transformer to induce rotor voltages across an air gap. The resolver does not use any electronic components, therefore it's very robust with a high temperature range, and is inherently shock resistance due to its design. A resolver is mostly used in harsh environments.
The optical encoder on the linear actuator motor uses a rotating shutter to interrupt a beam of light across an air gap between a light source and a photodetector, over time the wear associated with the rotating shutter reduces the longevity and reliability of the encoder.

The application will determine whether a resolver or an encoder is needed. Encoders are more accurate and are easier to implement so they should be the first choice for any application. The only reason to choose a resolver is if environmental and longevity requires it.

Anaheim Automation provides many different accessories for our linear servo motor. These accessories include a brake, encoder, connector, cable and a handheld interface unit.

The linear servo motor brake is a 24vdc system. These linear actuator motor brakes are perfect for any holding applications. They are available on any Anaheim Automation linear actuator motor, and are already attached to the rear of the linear actuator motor. The linear actuator motor brakes have a low voltage design for applications that are susceptible to weak batter, brown out, or long wiring runs. When electric power is applied to the linear actuator motor brake the armature is pulled by the electromagnet force in the magnet body assembly, which overcomes the spring action. This allows the friction disc to rotate freely. When electrical power is interrupted, the electromagnetic force is removed and the pressure spring mechanically forces the armature plate to clamp the friction disc between itself and the pressure plate.

Anaheim Automation's linear actuator motor is designed with a 2500 counts per revolution quadrature encoder, with a resolution of 10,000 pulses per revolution.

Anaheim Automation's linear actuator motor comes with all the necessary connectors to connect to another company's servo driver or an Anaheim Automation servo driver. These linear actuator motor connectors can also be purchased separately if they are lost. Please refer to the user's guide for a specific part number.

linear actuator motor cables can be made with the supplied linear actuator motor connector, or can be purchased from Anaheim Automation. The linear actuator motor cable comes with a standard length of 5M but can be adjusted to any length required.

The steam engine governor is considered the first powered feedback system that used a gain value so it is considered the first servo mechanism. The word linear servo motor comes from the French phrase "Le Servomoteur" or the "slave motor". The first known record of its use was by JJL Farcot in 1868 to describe steam engines and hydraulics for use in steering a ship.

PLEASE NOTE: Technical assistance regarding its linear actuator motor product line, as well as all the products manufactured or distributed by Anaheim Automation, is available at no charge. This assistance is offered to help the customer in choosing Anaheim Automation products for a specific application. However, any selection, quotation, or application suggestion for a linear actuator motor, or any other product, offered from Anaheim Automation's staff, its' representatives or distributors, are only to assist the customer. In all cases, determination of fitness of the custom linear actuator motor in a specific system design, is solely the customers' responsibility. While every effort is made to offer solid advice regarding the linear actuator motor product line, as well as other motion control products, and to produce technical data and illustrations accurately, such advice and documents are for reference only, and subject to change without notice.

The following information is intended as a general guideline for the installation and mounting of the linear servo motor. WARNING - Dangerous voltages capable of causing injury or death may be present in the linear servo motor system. Use extreme caution when handling, testing, and adjusting during installation, set-up, tuning, and operation. It is very important that the wiring of the linear actuator motor be taken into consideration upon installation and mounting.

Subpanels installed inside the enclosure for mounting linear actuator motor system components, must be a flat, rigid surface that will be free from shock, vibration, moisture, oil, vapors, or dust. Remember that the linear actuator motor and amplifier will produce heat during work, therefore, heat dissipation should be considered in designing the system layout. Size the enclosure so as not to exceed the maximum ambient temperature rating. It is recommended that the servo amplifier be mounted in an upright position, providing adequate airflow. The linear actuator motor should be mounted in a stable fashion, secured tightly. NOTE: There should be a minimum of 10mm between the servo amplifier and any other devices mounted in the system/electric panel or cabinet. There should be at least 10mm space in the lateral direction and 50mm space in the longitudinal direction, between the linear actuator motor amplifier and other electronic/electrical devices. For multi-axis systems, mount in the panel left to right according to power utilization (highest to lowest). If power utilization is unknown, mount from left to right based on Amp rating.

NOTE: in order to comply with UL and CE requirements, the linear actuator motor amplifier must be grounded in a grounded conducive enclosure offering protection as defined in standard EN 60529 (IEC 529) to IP55 such that they are not accessible to the operator or unskilled person. As with any moving part in a system, the linear actuator motor should be kept out of the reach of the operator. A NEMA 4X enclosure exceeds those requirements providing protection to IP66. To improve the bond between the power rail and the subpanel, construct your subpanel out of a zinc-plated (paint-free) steel. Additionally, it is strongly recommended that the linear actuator motor amplifier be protected against electrical noise interferences. Noise from signal wires can cause mechanical vibration and malfunctions.

The following environmental and safety considerations must be observed during all phases of operation, service and repair of a linear servo motor system. Failure to comply with these precautions violates safety standards of design, manufacture and intended use of the linear servo motor and amplifier. Please note that even a well-built linear actuator motor products operated and installed improperly, can be hazardous. Precaution must be observed by the user with respect to the load and operating environment. The customer is ultimately responsible for the proper selection, installation, and operation of the linear actuator motor system.

The atmosphere in which a linear actuator motor is used must be conducive to good general practices of electrical/electronic equipment. Do not operate the linear actuator motor in the presence of flammable gases, dust, oil, vapor or moisture. For outdoor use, the linear actuator motor and amplifier must be protected from the elements by an adequate cover, while still providing adequate air flow and cooling. Moisture may cause an electrical shock hazard and/or induce system breakdown. Due consideration should be given to the avoidance of liquids and vapors of any kind. Contact the factory should your application require specific IP ratings. It is wise to install the linear actuator motor and amplifier in an environment which is free from condensation, electrical noise, vibration and shock. Additionally, it is preferable to work with the linear actuator motor/amplifier system in a non-static protective environment. Exposed circuitry should always be properly guarded and/or enclosed to prevent unauthorized human contact with live circuitry. No work should be performed while power is applied. Don't plug in or unplug the connectors when power is ON. Wait for at least 5 minutes before doing inspection work on the linear actuator motor system after turning power OFF, because even after the power is turned off, there will still be some electrical energy remaining in the capacitors of the internal circuit of the linear actuator motor amplifier. Plan the installation of the linear actuator motor and amplifier in a system design that is free from debris, such as metal debris from cutting, drilling, tapping, and welding, or any other foreign material that could come in contact with circuitry. Failure to prevent debris from entering the linear actuator motor system can result in damage and/or shock.

NOTE: Meeting CE Requirements requires a ground system, and the method of grounding the ac line filter and the linear actuator motor amplifier must match. Failure to do this renders the filter ineffective and may damage.

The following information is intended as a general guideline for wiring of the Anaheim Automation linear servo motor product line. Be aware that when you route power and signal wiring on a machine or system, radiated noise from the nearby relays, transformers, and other electronic devices can be induced into motor and encoder signals, input/output communications, and other sensitive low voltage signals. This can cause systems faults and communication errors. WARNING - Dangerous voltages capable of causing injury or death, may be present in the linear servo motor amplifier. Use extreme caution when handling, wiring, testing, and adjusting during installation, set-up, tuning, and operation. Don't make extreme adjustments or changes to the linear actuator motor amplifier parameters, which can cause mechanical vibration and result in failure and/or loss. Once the linear actuator motor is wired, do not run the servo amplifier by switching On/Off the power supply directly. Frequent power On/Off switching will cause fast aging of the internal components in the servo amplifier, which will reduce the lifetime of linear actuator motor system. It's required to use reference signals to control the running of the linear actuator motor amplifier.
Strictly comply with the following rules:

- Route high-voltage power cables separately from low-voltage power cables.
-Segregate input power wiring and linear actuator motor power cables from control wiring and motor feedback cables as they leave the servo amplifier. Maintain this separation throughout the wire run.
-Use shielded cable for power wiring and provide a grounded 360 degree clamp termination to the enclosure wall. Allow room on the sub-panel for wire bends.
- Make all cable routes as short as possible.
- Single point grounding is required when mounting the linear actuator motor and servo amplifier, and grounding resistance should be lower than 100?.
- It's prohibited to apply power input noise filter between servo amplifier and linear actuator motor. Factory made cables are recommended for use in our linear actuator motor and amplifier systems. These cables are purchased separately, and are designed to minimize EMI. These cables are recommended over customer-built cables to optimize system performance and to provide additional safety for the linear actuator motor system and the user.
NOTE: Meeting CE Requirements for a linear actuator motor and amplifier system requires a ground system, and the method of grounding the ac line filter and the servo amplifier must match. Failure to do this renders the filter ineffective and may cause damage to the filter. For grounding and filter suggestions, please contact the factory.

WARNING - To avoid the possibility of electrical shock, perform all mounting and wiring of the linear actuator motor and amplifier system prior to applying power. Once power is applied, connection terminals may have voltage present, even when the linear actuator motor and amplifier are not in use.
