Direct Drive Brushless Servo Systems

The Dynaserv DR Series provides the user with a high performance direct drive servo system with resolver feedback. Each of the 13 models includes a direct drive motor, integral resolver, microprocessor based drive and a 10 foot motor-to-drive cable.

The DR Series motor is brushless and without gears allowing for long, maintenance-free operation. The cross roller bearing design can support up to 4 tons of compression load and 295 ft-lbs of overhung load. The center hole in the motor is up to 6 inches in diameter and can be used to simplify system wiring.

The user can elect to operate the DR Series in either a position, velocity or torque mode. In the position mode, the drive accepts step and direction input from any Compumotor indexer or user-supplied pulse source. Operating in the velocity mode requires a ±10VDC input and torque mode requires a ±8VDC input.

High performance closed loop operation is obtained with a sophisticated I-PD digital and analog control algorithm. The analog velocity loop provides high bandwidth for excellent system response. The digital position loop simplifies position control and optimizes system accuracy.

A built-in test mode and position/velocity monitors allow for convenient and efficient tuning.

The DR Drive is fully protected against open and short circuits, overcurrent, overvoltage and overtemperature. A seven segment LED indicator provide the user with the status and diagnostic information from the front panel.
