PM Drum Brakes

Features

These short stroke, direct acting electromagnetic brakes, require low maintenance and are capable of high rates of operation (up to 1200 operations per hour). Fast action or delayed operation is possible with additional control gear. These versatile brakes can be operated from AC or DC supplies, and can be supplied with a wide range of accessories, including manual and hydraulic operation, and condition monitoring. Brakes are electrically released, and have torque applied by a heavy duty compression spring. All types can be modified to enable operation in any plane on horizontal or vertical shafts. Brakes can be CSA approved on request.

  • It can be supplied for operation in many hostile environments, in ambient temperatures -40°C to +200°C.
  • The encapsulated coil has proved one of the most reliable available.
