Brake Control Gear

Brake control gear can be supplied for use with DC magnetic brakes with one or more of the following functions.

  • Rectify the AC supply (1ph or 3ph) to provide dc for the brake coil.
  • Reduce the brake operating time, eg to give a fast response on hoist brakes.
  • Reduce the brake release time.
  • Reduce the brake voltage after operation, to reduce brake coil heating, eg if duty cycle is arduous or ambient temperature is high.

Brake control gear comprises a combination of the following components depending on the application:

  • Silicon or selenium rectifier
  • AC or DC correction
  • Surge suppression components
  • Solid state or pneumatic timers
  • Resistor
  • Transformer
  • Terminals and fuses
