The servo electric motor is a closed-loop servomechanism that uses position feedback in order to control its rotational speed and position. The control transmission is the insight, either analog or digital, which represents the final position command for the shaft.
Servo drives are designed to power and manage performance of electric powered servomechanisms. They particularly monitor feedback indicators and continuously adjust to deviations from the anticipated behavior of closed loop systems. This helps to improve efficiency through faster acceleration prices and more precise quickness and position control.
AC servo drives are particularly created for AC motors, and offer the added benefit of motor opinions. After receiving and transmitting indicators to produce movement, these drives also receive and adjust 
to reports from sensors on electric motor status. In providing constant adjustment, they amplify functionality with regards to the required velocity, torque, and placement, as well as stiffness, damping, and opinions gain in AC servo motors and control systems.
The Ever-power category of brushless servo systems is fully digital and offers a rich set of features to cover a wide range of applications. There are eight standard servo motors which can be operated in combination with among three standard servo drives.
The Ever-power brushless motors add a 2,500 series incremental encoder with quadrature data signals (A+, A-, B+, B-) and a marker pulse (Z+, Z-). All three indicators have a range driver output leading to 10,000 pulses per revolution plus index indicate as the typical resolution inside the drive. Each servo electric motor also has one connector for the encoder and another connector for the motor power and optional 24 VDC spring-set holding brake.
SureServo Family
The servo drives can be configured for a wide selection of command sources including analog torque, analog velocity, “step and direction” or “along” pulse position, quadrature encoder follower, and built-in motion controller with preset position, velocity, or torque. Presets can be selected with discrete inputs or altered with the MODBUS serial interface.
Configuration and diagnostics of the servo drives can be accomplished with the integrated keypad/display or the easy-to-make use of SureServo Pro software on a Windows environment.
