1.5.1 Electromagnetic brake working principle
Motor shaft (9) is connected with shaft sleeve (4) by passing through the flat key. And shaft sleeve
(4) is connected with brake pad (3) by passing through the splines. When the stator (11) is block
out, the force produced by the pressure spring (10) would act on the armature (8) which makes
rotated the brake pad (3) driven by the motor shaft connected closely between the armature (8)
and cover plate (5). As a result the braking torque is created. There will be a air gap Z between
the armature and the stator at that moment. When the brake needs to be relaxed, the stator is
applied with direct current and the magnetic field would attract the armature (8) to move towards
the stator. The movement of armature compresses the pressure spring (10) which cause the
loosening of the brake pad (3) by that time and the brake is released.
