The servo electric motor is a closed-loop servomechanism that uses position feedback in order to control its rotational speed and position. The control signal is the insight, either analog or digital, which represents the ultimate position control for the shaft.
Servo drives are designed to power and manage performance of electric servomechanisms. They specifically monitor feedback signals and continuously adapt to deviations from the expected behavior of closed loop systems. This can help to improve overall performance through faster acceleration prices and more precise quickness and position control.
AC servo drives are particularly designed for AC motors, and provide the added advantage of motor feedback. After getting and transmitting indicators to produce movement, these drives also get and adjust to reports from sensors on motor status. In providing constant adjustment, they amplify performance with regards to the required velocity, torque, and placement, as well as stiffness, damping, and feedback gain in AC servo motors and control systems.
The Ever-power family of brushless servo systems is fully digital and will be offering a rich set of features to cover a wide selection of applications. There are eight standard servo motors which can be operated in combination with one of three standard servo drives.
The Ever-power brushless motors add a 2,500 line incremental servo motor encoder with quadrature data signals (A+, A-, B+, B-) and a marker pulse (Z+, Z-). All three signals have a line driver output leading to 10,000 pulses per revolution plus index tag as the typical resolution within the drive. Each servo electric motor also offers one connector for the encoder and another connector for the engine power and optional 24 VDC spring-set keeping brake.
The servo drives can be configured for a wide variety of command sources including analog torque, analog velocity, “step and direction” or “along” pulse position, quadrature encoder follower, and built-in movement controller with preset position, velocity, or torque. Presets could be selected with discrete inputs or modified with the MODBUS serial user interface.
Configuration and diagnostics of the servo drives could be accomplished with the integrated keypad/display or the easy-to-make use of SureServo Pro software program on a Windows environment.
