Abstract

A washing machine has a rotating drum in which articles to be washed are contained and a door providing access to the drum. The door is held closed by a safety latch actuated by an electromagnet which operates at a single predetermined applied voltage. The current applied to the electromagnet is dependent on the rotational speed of the drum which is driven by a continuous current permanent magnet induction motor. Operation of the safety latch is safer and more consistent than devices using eg. a micro-switch to switch off the motor when the door is opened.
