PCT No. PCT/EP86/00077 Sec. 371 Date Nov. 4, 1986 Sec. 102(e) Date Nov. 4, 1986 PCT Filed Feb. 15, 1986 PCT Pub. No. WO86/05336 PCT Pub. Date Sep. 12, 1986.A control circuit for controlling a brushless motor for a washing machine comprises AC main voltage, a phase-trimming circuit for trimming the AC main voltage and supplying the trimmed AC main voltage to the stator windings of the brushless motor, depending on a control voltage derived from a rotor position sensor of the brushless motor. The phase-trimming circuit changes the polarity of the trimmed AC main voltage so that a first polarity is supplied to a first stator winding and a second polarity is supplied to a second stator winding of the brushless motor. |
