Drive motor function
When the stator winding is charged, a magnetic
field will occur, which in turn will rotate the motor at
a fixed RPM depending upon the number of poles
in the winding. The 12-pole winding gives the
wash speed and the 8-pole winding in the same
motor gives the distribution speed. The separate
4/2-pole motor gives the extraction speeds. When
operating with load, the speed deviates slightly
from the synchronous (no-load) speed. This
difference is called the slip and is usually
expressed as a percentage of the synchronous
speed. The motors will work satisfactory at
nominal voltage +10% – -15%.
How to remove motors
Loosen the spring loaded set screw. Lift the motor
unit and detach the V-belts. Dismount the bracket
holding the motor hinge shaft. Lift out the motor
bracket with motors mounted. Loosen the
mounting screws of the extract motor and the set
screws. Lift off the V-belts. Now remove the
mounting screws for each motor.
How to mount motors
Place the motors on the table or bench with the
mounting holes upwards. Mount the mounting
bracket to the wash/distributiont motor. Position
the other motor and fasting the mounting screws.
Mount the V-belts. Tighten the belts. Mount the
bracket with motors in the machine in the opposite
way as outlined above in ’’How to remove motors’’.
