4.14.1 AR.. and AT.. centrifugal and friction couplings
AR.. friction
coupling
Drives with a friction coupling consist of a standard gear unit and motor/variable speed
gearmotor with an adapter installed between them. This adapter accommodates the fric-
tion coupling. In gearmotors with a multi-stage gear unit, the friction coupling may be
located between the first and second gear units. On delivery, the slip torque is set indi-
vidually according to the drive specifications.
The following figure shows a drive with friction coupling and W: speed monitor
W speed monitor:
The speed monitor is used with constant-speed gearmotors and is connected to the
encoder in the adapter.
WS slip monitor:
The slip monitor is used with the following components:
• Speed-controlled motors with speed sensor
• VARIBLOC
