induction motors
Hi Phil,
traditionally two types of motor have been used as the main motor in european washing machines. Induction motors and universal or brush motors as they are commonly called.
Basically all the quieter machines, older continental machines, Philco/bendix, zanussi etc used the induction motors, whilst hoover hotpoint etc the noiser machines used brush motors.
Brush motors are used in conjunction with an electronic control circuit, this enables the machines to have wash, distribution and several or variable spin speeds. Hence hoover electronic 1100, the only electronic part is the motor speed control. the programme is still mechanically controlled.
Induction motors require the motors to have seperate internal windings for wash and spin speeds.
In the past few years modern electronics has enabled manufacturers to develope these types of motor, such as the lg machines and modern inverter motors.
Sorry Phil i could go on at length about the engineering, but If you want a greater explanation of this subject, the Haynes washing machine manuals give a good understandable explanation of this subject and the other functions of the automatic washing machine. A good starting point and bed time read for many of us in the uk, some good photographs too.
Well Phil I hope this helps, feel free to ask for any more information.
