Rex Engineering: Although you will never have a need to disassemble the brake mechanism, it is easier to see how it works if we break it down into the individual components.

This is all (4) of the brake components removed form the gearmotor

This is the two slot gear mounted to the motor armature. It is attached by an

assembly that allows it to act as a clutch. It will allow the gear to slip to relive any stress

that would be cause by a sudden stop

With the brake components removed, we can see the lower

ball bearing and the two shaded poles

Ball Bearing

Shaded poles

The motor armature with the two slot gear has been added

The short locking arm and spring has been installed. Notice

that the spring pulls the arm towards the center and into a slot

Gear box

The brake armature has been added. Observe the

armature resting against the locking arm and the gap of the armature to the motor frame when the motor is

de-energized

The brake armature has been added. Observe the armature

resting against the motor frame and the lack of a gap of the armature to the motor frame

when the motor is energized

The upper bearing assembly is now installed and the brake is completely assembled on the

motor. The gearmotor is ready to

install in the stove
