Electromagnetic brakes on drum motors are operated via rectifiers. Different versions are available depending on the applications: Half-wave and bridge rectifiers for standard applications as well as fast acting and multiswitch rectifiers for applications in which short opening delay times are necessary.

Note: Rectifiers, just like electromagnetic brakes, are available only for asynchronous drum motors.

Every rectifier is an external component that must be covered or installed in a control box as close to the brake as possible.
