2-2. Structure and Operation
The MSU type has the structure shown in Fig. 1, and the MSCP type has the structure shown in
Fig. 2.
③ ⑧ Clutch / brake field with b
uilt-in coil
(clutch field ② for MSCP type)
is fixed to the inner
surface of the casing, respectively, ④ input shaft
(⑥ for
MSCP type)
and ⑨ output shaft
(⑪
for MSCP type)
. Is supported by ②⑤ ball bearings
(MSCP type ③⑦⑩).
Fo
r the MSU type, the brake disc assembly is screwed to the brake field. The ⑦ rotor assembly
is fixed to the input shaft by the ⑥ parallel key, and the ⑪ ar
mature hub
(⑫ for the MSCP
type)
is fixed to the output shaft by the ⑩ parallel key
(⑨ for the MSCP t
ype
).
⑬ Clutch armature
(MSCP type is ⑧)
and ⑫ Brake armature are attached to the spline part
of the armature hub via a guide.
When the clutch side coil is energized, magnetic flux flows between the clutch field, rotor, and
clutch armature, the armature is attracted to the rotor, the clutch is engaged, and the rotation
of the input shaft is transmitted to the output shaft.
The auto-gap device keeps the air gap constant even if the friction surface wears.
