ELECTRONICALLY COMMUTATED MOTOR, METHOD OF OPERATING SUCH, CONTROL CIRCUIT, LAUNDRY MACHINE AND DRIVE THEREFOR ABSTRACT OF THE DISCLOSURE An electronically commutated motor for the energization by DC in both a high speed mode and a low speed mode at a current not a plurality of winding stages each with a plurality of winding turns only a first portion of which is commutated in a first sequence in a high speed mode and a predeterminately greater portion of which is commutated in a second sequence different from the first sequence when the motor is energized in the low speed mode. A permanent magnet rotor is rotatably driven in one direction in the high speed mode so as to develop a first torque at the preselected current level when only the first portion of the winding turns of the winding stages are commutated in the first preselected sequence. In response to commutation in the second sequence of the predetermin- ately greater portion of the winding turns the rotor is rotatably driven alternately in opposite directions in the low speed mode so as to develop a second torque predeterminately greater than the first torque at a current not significantly greater than the preselected level. A method of operating such motor, a control circuit therefor and the use of such a motor in laundry machines and drives therefor are also disclosed.
