3.3.2. Motor
The motor consists of an engine block and the engine shaft with the impeller assembly. The circuit for power
supply is designed for the maximal mechanical performance according to the characteristics or the nameplate of
the pump. The cable inlets as well as the circuit are sealed resistant to jet water towards the pumped medium.
The shaft bearing is carried out by means of robust, maintenance-free and permanently lubricated antifriction
bearings.

3.3.3. Monitoring devices
Temperature sensor
The pump type is equipped with a temperature sensor set in the motor windings, which switches the motor off in
the event of overheating of the winding.
After cooling, the motor will restart automatically.
The triggering temperature of the sensors for standard version motors is 130°C.
Checking direction of rotation
No check is required for single-handed motors, since these always run in the correct direction.
Three phase motors have the correct direction of rotation if connected to a clockwise rotating field (U, V, W -> L1,
L2, L3). HOMA switchgears check the circuit for a clockwise rotating field. If there is no clockwise rotating field,
the red LED flashes. Two phases have to be interchanged at the input of the switchgear. For smaller pumps, the
check can be carried out by observation of the start-jerk.
