Driving method of brush-powered hybrid-excited motor and brush-powered hybrid-excited motor

摘要

PPROBLEM TO BE SOLVED: To provide a brushed hybrid excitation motor, in which a rotor has an armature structure allowing motor characteristics to be changed and a stator is configured by a permanent magnet and a yoke, and a method of driving the brushed hybrid excitation motor. PSOLUTION: In a front housing 2a, a stator 20 is provided with an upper magnetic flux controlling coil 23a and a lower magnetic flux controlling coil 23b. In the stator 20, a field magnet MG that creates a magnetic pole of one polarity and a field core 22 that projects into an inner periphery are alternately disposed. The upper magnetic flux controlling coil 23a and the lower magnetic flux controlling coil 23b are wound in a circumferential direction in positions on both sides of the field magnet MG and the field core 22. An armature rotor 10 is also provided that includes a commutator 14 in sliding contact with a brush 21b disposed on the inner peripheral side of the stator 20. Inter-linkage flux towards the field core 22 can be increased or decreased by changing the direction and value of currents flowing to the upper magnetic flux controlling coil 23a and the lower magnetic flux controlling coil 23b.
