MOTOR

Direct current version with permanent magnets. The stator includes the ferroxdure permanent magnets. The rotor contains the laminated soft iran Gare, the coils and the commutator. Two brush hotders, which contain 2 carbon brushes, are placed opposite each other. The carbon brushes rest on the

commutator to provide a sliding contact to pass current.

The motor shaft is equipped with an insulated pulley, Service Code ofthe insulated pulley does not appear because it is

not replaceable.

The motor is ted by the "Control unit" which supplies the different vortages required, depending on the speed.

r ROTATION TIME," '

( Normal:

The normal rhythm is effected by means of the fast cam disc (3) wh ich, by means of a mechanical arrangement in the

( timer, allows slowcam disc 5 to operate as a fastone. Then, by closing contacts 3.25 and 5.25there will be 7.5" rotation in

clockwise direction, and by closing contacts 3.33 and 5.35 there will be 7.5" rotation in counter-clockwise direction,

while with contact 1-31 open there will be a stop of 7.5".

( ~

The slow rhythm is obtained by the closing of the same contacts of the normal rhythm and of the contacts 4-24 and 2-32. When contacts 4-24 and 2-32 are closed there is no revolution of the drum tor 3", as the motor is not ted by the electronic

( mode. When contacts 4-24 and 2-32 are open, the drum stops tor 12".

( DRAIN PUMP

The reverse revolution of the drum, as previously described, takes plaGe by the closing of contacts 3-23,5-25 I 3-33 and 5-35.

This pressostat will switch on the drain pump when the quantity of water in the tub exceeds approx. 36 liters.

TIMER

A Graulet type with 60 impulses -Type 914/1393.

The timer programme chart includes 3 basic programmes (normal, delicate and wool programme), 3 stop positions and 3

( start positions. Besides, on positions 26 and 44 there is an optional rinse stop (stop with water in the tub).
