Bearing Mounted Electric Clutch/Brake Assemblies and Operation
Components
An electric clutch/brake or clutch consists of
three primary components:
1. Field Assembly
The clutch's "power" source contains the
coil which generates magnetic force. Most
common applications require a 12 volt DC
coil, although other voltages are available.
2. Rotor Assembly
Generally, the input of the clutch. Includes a
keyed hub which mates with the keyway in
the drive shaft. The rotor transmits torque
from the drive shaft to the output, or
armature assembly.
3. Armature Assembly
Generally, the output of the clutch. Also
contains the mechanical brake in a
clutch/brake assembly. The armature
transmits torque from the rotor to the
driven load.
The sleeve is a secondary component. This
sleeve serves as a spacer between the rotor
and the field assembly, and is also a support
for the field assembly bearing.
