Solid State Motor Brakes provide fast, smooth, frictionless braking of
squirrel cage motorsby injecting controlled DC current into the motor
windings, after mains contactor open.
This induces a stationary magnetic field which exerts a braking torque
on the rotor.
The SMB is the ultimate replacement for the old electrical braking
systems such as Reversing (which may result in reversing the
rotation of the motor) or Regenerative braking
(which requires resistors to absorb the energy).
The SMB can be used with mechanical brakes to softly bring the motor speed to zero before
operating a mechanical brake.
