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 ca-
ble entries and the lead are sealed watertight against the
conveyed medium. The shaft bearings are robust, mainte-
nance-free and permanently greased roller bearings.

3.3.3. Monitoring systems
Direction of rotation control
No check is necessary for 1ph motors , since these al-
ways run in the correct direction of rotation.
3ph motors run in the correct direction of rotation when
connected to a anticlockwise rotating field (U, V, W -> L1,
L2, L3). HOMA switchgear checks the grid for a clockwise
rotating field. 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
clockwise if the direction of rotation is correct.
The direction of rotation of the pump is correct if the pump
moves clockwise because, seen from above, the motor
starts in the anticlockwise direction.
Warning of rotating blade wheel.
Do not touch the rotating blade wheel or reach
through the discharge outlet into the pump chamber!
During operation, never reach into the pump cham-
ber or touch rotating parts. Before maintenance or
repair work, shut the machine off and let the rotating
parts come to a standstill.
It is also possible to check the direction of rotation with
a "motor and phase rotation indicator" . This measuring in-
strument is held externally against the motor housing of
the running pump: it shows the direction of rotation with
an LED.
