5.3.2 Braking operation principle
：
As follow picture
：
The brake constitute by magnetic yoke 6 ,magnet exciting coil,7 , the
spring 2, the brake disc 5,the armature 1, the gear sleeve 4, the mounting screw 3,And so
on .The brake is mounted on the end cap of the motor and the mounting screw is adjusted to
the specified air gap value.
When magnet exciting coil 7 for brake on power
，
The coil generates a magnetic field to
to attract the armature 1 to the yoke assembly 6, and the armature 1 is disengaged (released)
from the brake disc 5.At this time, the motor drive shaft is normally started and operated
with the brake disc 5.When the magnet exciting coil 7 is de-energized, the magnetic flux
disappears, the armature 1 is released, and the spring 2 is pressed against the armature 1,
and the friction plate on the brake disc is pressed to generate frictional force for braking
purposes.
