Drive motors

Drive motor description

The four-speed operation of the wash cylinder is

achieved by two motors. One 2-speed motor for

wash speed (12-pole drive) and distribution speed

(8-pole drive) and one 2-speed motor for

extraction speeds (4-pole drive, low speed and

2-pole, high speed). The motors are mounted on a

motor bracket with the wash and distribution motor

fixed to the bracket and the extract motor in slots

which allow adjusting the distance between the

two motors for proper belt tension by adjusting

screws. For silent operation the motor bracket is

mounted to the base of the machine by rubber

bushings. Correct tension to the main belt,

between the cylinder and the extract motor, is

obtained by the weight of the motors and the

motor bracket and by the spring loaded set screw.

Drive motor construction

The motor consists of stator, rotor and end-shields

with ball-bearings. The stator and the rotor

consists of plates, insulated from each other and

welded together. The stator is provided with slots

in which the 8-pole and 12-pole resp. the 2- and

4-pole windings are wound. The windings are

impregnated with a temperature-resistant sound-

insulating resin varnish according to class B. The

end-shields are die-cast. The ball bearings are

permanently lubricated.
