3.3.2. Motor
The three-phase asynchronous 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

The unit is equipped with various monitoring safety equipment. The following table shows an overview of the
available options. Depending on the size of the discharge nozzle, options may vary.

Temperature sensor
In the standard version, the temperature sensors are connected internally in the motor so that no special
connection is necessary.. After cooling, the motor will restart automatically. The triggering temperature 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 rotating if connected to a clockwise rotating field (U, V, W -> L1,
L2, L3). HOMA switchgears check the circuit for 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. For this, place the pump vertically onto the floor, slightly
onto the edge and switch on for a short time. When seen from above, the pump rebounds slightly anticlockwise in
correct direction of rotation.
The direction of rotation is correct if the pump moves anticlockwise, since the motor starts clockwise when seen
from above.
Warning - rotating impeller!
Do not touch the rotating impeller or do not reach the pump chamber through the pressure socket!
Never put your hands into the pump chamber or touch the rotating parts in operating mode. Switch the
machine off and let the rotating parts come to gridlock before carrying out maintenance work or repair
work!
