Unbalance motors are asynchronous AC Motors with pairs of
centrifugal weights fitted to the ends of the motor shafts.
The size of the unbalance and with it the amplitude of the
oscillation by the working unit can be adjusted by shifting
the centrifugal weights when the motor is at a standstill.
A stable, rigid motor shaft and roller
bearings with a long service life allow the unbalance motors
to be operated continuously even under difficult operating
The unbalance motors are supplied in 2,4,6
and 8 Pole versions. This means the motor speed and therefore
the oscillation frequency can be ideally selected to suit
each particular application.
The unbalance motors are also available
in a special version for mains voltages up to 690V and for
a mains frequency ranging from 50 Hz to 60 Hz.
