Abstract

The washing machine drive system comprises a pole changeable alternating current motor (7) which drives a drum (3) of the drum-type washing machine (1) through an induction coupling (15) and a rotation speed-reducing belt transmission (5). A programme control system (11) switches on the motor (7) with low pole number (for example 2) in spin- drying operation and with high pole number (for example 12) in washing operation. The drive-output rotation speed of the induction coupling (15) is kept both in spin-drying operation and in washing operation at a rotation speed value predetermined by the programme control system (11), by a rotation speed regulator circuit (17). The rotation speed regulator circuit (17) gives off direct current pulses to the induction coupling (15), the pulse rate or pulse width of which is variable in dependence upon the actual rotation speed of the induction coupling (15).
