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 perfor-
mance 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 medi-
um. The shaft bearing is carried out by means of robust,
maintenance-free and permanently lubricated antifriction
bearings.

3.3.3. Monitoring devices
Temperature sensor
All pumps in alternating current version are provided with
a temperature sensor set in the motor winding. For all
pumps, the temperature sensors are connected internally
in the motor, so that no special connection is necessary.
After cooling down, the motor automatically switches on
again.
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 grid for clockwise rotation.
If there is no clockwise rotating field, the red LED lights
up. Two phases are to be exchanged at the input of the
switching device. For smaller pumps, the control can be
done by observing the start jerk. For this, place the pump
vertically onto the floor, slightly onto the edge and switch
on for a short time. When viewed from above, the pump
will slightly jerk in the correct direction of rotation coun-
terclockwise
The correct direction of rotation of the pump is given
when the pump is moving in a clockwise direction, as the
motor starts counterclockwise when viewed from above.
ATTENTION
The direction of rotation
is correct if the
impeller/propeller rotates
in a clockwise manner
when viewing down from
top of the placed unit
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!
Furthermore it is possible to check the direction of rotation
with a 'motor and phase rotation indicator'. This measur-
ing device is held towards the engine block of the running
pump from externally and shows the direction of rotation
by means of LED.
Automatic float switch (version...A)
Version with automatic float switch HOMA Nivomatik, AS
floater, 10 meter connection cable, switchgear and manu-
al-0-auto switch. The single phase pumps are furthermore
provided with integrated condensers and connector. The
three phase pumps are provided with a CEE reversing
plug for rotational direction
Motor cooling
Sufficient motor cooling is also provided for in snore op-
eration due to the water jacket with pressure connection
on top.
ATTENTION
The start reaction is
anti clockwise
