3.3.2. Motor
The three-phase asynchronous motor consists of a stator
and the motor shaft with the rotor set. The power sup-
ply cable is designed to handle the maximum mechanical
power in accordance with the characteristic line or name
plate of the mixer. The cable entry points and the cable
are sealed water-tight against the conveyed medium. The
shaft bearings are robust, maintenance-free and perma-
nently greased roller bearings.
