3.3.2. Motor
The three-phase asynchronous motor consists of an en-
gine block and the engine shaft with the impeller assem-
bly. The circuit for the power supply is designed for the
maximal mechanical performance according to the char-
acteristics or the nameplate of the pump. The cable in-
lets as well as the circuit are sealed resistant to jet water
with respect to the pumped medium. The shaft bearing
is carried out by means of robust, maintenance-free and
permanently lubricated antifriction bearings.

3.3.3. Monitoring equipment
Temperature sensor
The pump type FW/TP4/1 is provided with a temperature
sensor set in the motor winding, which switches the mo-
tor off in the event of overheating of the winding. After
cooling, the motor will restart automatically. The pump
type FW-TP8/1 is provided with a switchgear with a mo-
tor protection switch. This switches off the pump in the
event of overload.
Rotational direction check
No check is required for single-phase motors, since these
always run in the correct direction of rotation. Three phase
motors have the correct direction of rotation if connected
to a clockwise rotating field (U, V, W -> L1, L2, L3). HOMA
switchgears check the circuit for a 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 direc-
tion of rotation. The direction of rotation is correct if the
pump moves anticlockwise, since the motor starts clock-
wise 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
Warning - rotating impeller! Do not touch the rotating
impeller or do not reach into 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!
