Dynamic Brakes

for AC Motors 4-315KW, 220-690V

Solid State Motor Brakes provide fast, smooth, frictionless

braking of squirrel cage motors by injecting controlled DC

current into the motor windings, after mains contactor has

opened. This induces a stationary magnetic field which

exerts a braking torque on the rotor.

The SOLBRAKE is the ultimate replacement for the old

electrical braking systems such as 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 mechanical brakes to

softly bring the motor speed to zero before operating a

mechanical brake.

DC Injection Brakes Advantages at a Glance

  • Reduced stopping time - To increase production rate in machine tools and high inertia loads
  • Reduced stopping time - To increase safety in hazardous machines
  • Soft, smooth stopping, preventing wear and tear of mechanical parts
  • Adjustable braking torque, matching load size and required stop time
  • Auto stop, reducing motor heating
  • Maintenance free, highly reliable operation
  • Easy installation in electrical switchgear

DC Injection Brakes Typical Applications

  • Machine tools
  • Circular saws
  • Fast stopping of high inertia loads
  • Safety brakes
  • Large flywheel applications
