  • Control method for controlling a current vector controlled synchronous reluctance motor
    Patent number: 9209733
    Abstract: A current vector controlled synchronous reluctance motor and control method thereof, wherein the motor has a coil on each of the teeth. The coils form a U-phase winding, a V-phase winding and a W-phase winding. The phase windings receive a balanced three-phase current vector to induce closed magnetic field lines, such that the coils induce same magnetic poles adjacent to the rotor unit. Two short magnetic routes are formed along three adjacent teeth and the rotor unit. The efficiency of the reluctance motor is high.
    Type: Grant
