DC Injection Brake

SOLBRAKE

Solid State Motor Brake

10 - 820A, 208 - 690V

Solcons’ Solbrake DC injection brake uses direct current (DC) is to brake AC motors. The current is applied to the running motor as soon as the voltage is switched off.

Proving to be extremely effective and efficient when it comes to braking an AC motors such as in Machine tools, Circular saws, Stopping high inertia loads, Safety brakes and Large flywheel applications.

Adjusting the Braking Torque

You can achieve a very quick and smooth braking even in the event that you are running a motor at a high speed and with high loads. Whenever the AC voltage current is cut off the motor will be able to reach a standstill safely because there is no induced field to keep the motor rotating.

 The Solbrake - Solid State Motor Brakes are integrated into the motors’ control circuitry and provides fast, smooth, frictionless braking of standard three-phase squirrel-cage motors by injecting controlled DC current to the motor windings, after the mains line contactor has opened. This induces a stationary magnetic field, which exerts a braking torque on the rotor.

  • Stopping time can be similar to the time it takes to reach full speed on a Direct-On-Line starting. 
  •  Perfect matching of the brake to the driven load is enabled by adjusting braking torque and braking time.
  • Automatic sensing System turns the brake off automatically when the motor comes to a full stop. This minimizes the motor heating.
  • In addition, the wear and tear of mechanical parts is reduced significantly due to the softer and smoother stop that the Solbrake delivers.
