Regenerative DC Drives

Regenerative adjustable speed drives also known as four-quadrant drives, are capable of controlling not only the speed and direction of motor rotation, but also the direction of motor torque. This is illustrated below.

The term regenerative describes the ability of the drive under braking conditions to convert the mechanical energy of the motor and connected load into electrical energy which is returned (or regenerated) to the AC power source.

When the drive is operating in Quadrants I & III, both motor rotation and torque are in the same direction and it functions as a conventional non-regenerative drive. The unique characteristics of a regenerative drive are apparent in Quadrants II & IV. In these quadrants, the motor torque opposes the direction of motor rotation which provides a controlled braking or retarding force. A high performance regenerative drive, such as the Series 2230, is able to switch rapidly from motoring to braking modes while simultaneously controlling the direction of motor rotation.

Regenerative drives provide reversing without the use of a contactor. This reduces system cost while eliminating moving parts and greatly improving reversing and braking performance.
Although the regenerative drive eliminates the requirement of a contactor for reversing or normal operational braking, a contactor is used if dynamic braking is still required. Although regenerative braking stops the motor and it’s load faster under normal conditions, a dynamic brake may be required to stop the motor and it’s connected load in emergency stop conditions such as drive failure or if the drive enable is removed before the motor comes to a complete stop.
