THREE PHASE MOTOR
These washing machines are equipped with three-phase motor.
Compared with the commutator motor there are no brushes and the stator is delta connected
internally (see diagram).
The three-phase motor has a thermoprotector that cuts in turning off the supply to the power part of
the electronic card and therefore to the motor.
The photo and diagram below give the connection diagram of the windings.
