3.3.2. Motor
The rotary current asynchronous motor consists of a sta-
tor and a motor shaft with the rotor package. The elec-
trical supply line is designed for the maximum mechan-
ical power according to the curve or rating plate of the
pump. The cable entries and the line are sealed watertight
against pressurised water for the conveying medium. The
shaft bearing is provided via robust, maintenance-free and
permanently-lubricated roller bearings. All motors are also
supplied in explosion-protected design to ATEX Ex II 2 G
EExd.

3.3.3. Monitoring Equipment
The unit is equipped with various pieces of monitoring and
safety equipment. The following table shows an overview
of the options available. Options may vary, depending on
the size of the pressure joint.
Motor Type Motor Version
ET... Submerged motor, thermal monitoring of winding,
seal monitoring on oil reservoir
ET... EX Submerged motor, thermal monitoring of winding,
seal monitoring on oil reservoir, explosion-protected
Temperature Gauge
All pumps are equipped with a temperature gauge set in
the motor windings. In all pumps of the normal version,
the connections of the temperature gauge are directed
outwards through the connection cable and are connect-
ed via terminals T1 and T3 of the connection cable in the
control cabinet so that the motor automatically switches
on again after the motor cools down.
Instead of the standard gauge, the explosion-protected
designs have a temperature gauge set with a higher trig-
ger temperature that is to be connected via terminals T1
and T2 of the connection cable so that after triggering,
it manually resets via a special gate combination in the
switching gear.
The temperature gauge set must be connected in the
switching system that shuts this down when it overheats.

Sensors:

Direction of Rotation Check
All pumps have the correct direction of rotation when con-
necting to a dextrorotatory field (U, V, W -> L1, L2, L3).
HOMA switching devices check the mains for a dextroro-
tatory field. If there is no dextrorotatory field, the red LED
lights up. Two phases are to be swapped at the input of
the switching device. For smaller pumps, the check can
be done by monitoring the starting jolt. Do do this, put
the pump carefully on the floor on its edge and switch
on briefly. Seen from above, the pump slightly jolts in the
correct anticlockwise direction.
The pump has the correct direction of rotation if the pump
moves anticlockwise, as the motor starts in the clockwise
direction when seen 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
For large pumps, the direction of rotation can also be de-
tected by looking through the pressure joint into the pump
chamber.
