3.3.2. Motor
The motor consists of a stator and the motor shaft with the rotor set. The lead for supplying power is designed for
the maximum mechanical power in accordance with the characteristic curve or data plate of the pump. The cable
entries and the lead are sealed watertight against the conveyed medium. The shaft bearings are robust,
maintenance-free and permanently greased roller bearings.

3.3.3. Monitoring systems
Direction of rotation control
No check is necessary for 1ph motors, since these always run in the correct direction of rotation.
3ph motors run in the correct direction of rotation when connected to a clockwise rotating field (U, V, W -> L1, L2,
L3). HOMA switchgear checks the grid for a clockwise rotating field. If there is no clockwise rotating field, the red
LED is lit. Two phases are to be exchanged at the input to the switchgear. With smaller pumps, the check can be
made by observing the starting jerk. For this purpose, place the pump perpendicular to the floor, slightly on edge,
and switch on briefly. Seen from above, the pump jerks slightly anticlockwise if the direction of rotation is correct.
The direction of rotation of the pump is correct if the pump moves anticlockwise because, seen from above, the
motor starts in the clockwise direction.
