Electric Motors
3-phase Electric Brake Motors
Power Jacks can supply electric brake motors for all applications whether AC or DC motors are required.
The most popular motors used are 3-Phase AC Induction Motors, however we also supply 1-Phase AC Induction Motors, Servo Motors and DC Permanent Magnet Motors.
The brakes on these motors are primarily designed as holding brake. They are spring applied electrically released units (energise to release), which provide the fail safe operating characteristics such that on interruption, or failure of power supply, brake will engage and arrest the load.

Benefits
The brake units are a single disc type mounted on the non-drive end-shield of the motor and can be either DC or AC types (DC is the standard type). They are spring applied electrically released units (energise to release), which provide fail to safe operating characteristics such that on interruption, or failure of power supply, the brake will engage and arrest the load.
