SINGLE BRUSH TWO PHASES 2/2 POLE MAGNETIC RELUCTANCE VIBRATORY MOTOR AND SINGLE BRUSH COMMUTATOR

摘要

The invention disclosed a two phases 2/2 pole magnetic reluctance vibratory motor structure-One end of the coil in the stator connects to the commutator segnemt, the other connects to one of the poles of the power supply, and the brush connects to the other pole of the power supply. The rotor is composed by eccentric permanent magnets and sleeve. The stator is composed by the coils arranged on the opposite sides of the fixed shaft, and the rotor rotates on the fixed shaft via the sleeve. The fixed shaft not only don't superpose with the weight center of the rotor but also don't cross the linked line between the magnet poles of the rotor, thus compose the eccentric vibrator. The single brush commutator provides starting moment and steady operative moment to the eccentric rotor. After the center of gravity of the rotor being balance, the same motor structure can be used to ordinary drive motor, and the same single brush commutator can be used to the magnetic reluctance motor which has armature rotor, so that replaces the rotor position sensor of ordinary magnetic reluctance motor to drive high-power commutation circuit directly. This motor structure can be also used to mult-pole magnetic reluctance motor.
