A washing machine has a rotatable drum for holding items being washed and water for washing the items. The number of items in the drum and the amount of water in the drum may vary. Power is supplied from an inverter to a motor which rotates the rotatable drum. A speed control responsive to the inverter current regulates the drum rotating speed within a selected range.
