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 conditions.
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.
