DC Injection Brake: Solbrake


Ratings: 8-820A, 208-690V
The Solbrake Electronic Brake provides fast, smooth, frictionless braking of standard motors by injecting controlled DC current into the motor windings after the line contactor has opened. This DC current induces a stationary magnetic field which exerts a braking torque on the rotor.

DC Injection Brakes

The Solbrake is an ideal replacement for the old electrical braking systems including Reversing (which may result in reversing the motor rotation) or Regenerative braking (which requires resistors to absorb the energy). The Solbrake can be used with auxiliary mechanical brakes, use the Solbrake to gently bring the motor speed to zero before operating a mechanical brake as the holding brake.
