magnet exciting coil and so
on. The brake is mounted on the drive rack and adjusts the mounting screw to the specified
air gap value.
When magnet exciting coil 9 for brake on power
，
The coil generates a magnetic field to
draw the hollow bolt 4 to the magnetic yoke 2,hollow bolt 4 is separated from the brake disc
(release).Magnet exciting coil generates a magnetic field to absorb the magnetic magnetic
yoke 2, which separates the hollow bolt 4 from the brake disc. At this moment, the motor
will start and operate normally with the brake disc. When the magnet exciting coil 9 is off,
the flux disappears and the hollow bolt 4 is released, Spring 3 puts pressure on hollow bolt
4,The friction plate of the brake disc on the hub motor is pressed tightly and the friction
force is produced to achieve the braking purpose.
