YEJ electromagnetic brake Motors works: when the brake motor connected to the power supply, the brakes may also work. Due to the electromagnetic force, electromagnet attracts the armature and compression springs, brake disc to the armature-end cap off, motor up and running. When cut off power supply, electric brake magnets lose their magnetic attraction force, spring drive armature pressed discs, in the presence of friction torque, motor stops immediately. YEJ electromagnetic brake motor basic parameters: YEJ electromagnetic brake rated voltage: 380V YEJ electromagnetic brake motor rated frequency: 50Hz, 60Hz;
