REGENERATIVE DC Drive & Motor can be used instead of Servo equipment, and are cheaper.

REGENERATIVE DC Drives can be used instead of servo drives & motors in most of appilications, and they are cheaper than Servo Equipment.

REGENERATIVE Speed Controls for 1/4 ~ 1.5HP - 90V DC Motors with PM or Shunt Wound Field, open Chassis. Control Speed and Rotation direction electronically. 

Regenerative Drives are used in many applications where the Motor needs to move in both directions without Electromechanical Contactors and pumping back power to the Power Company during deceleration or when stopping.

Its 4 quadrants operation allows the motor to operate in both directions at full power, REGENERATIVE DC DRIVES CAN REPLACE SERVO-DRIVES IN MAY APPLICATIONS.
