Claims

[Scope of utility model registration request]

A permanent magnet stator having a plurality of magnetic poles, a rotor having the same number of excitation coils as the number of magnetic poles of the permanent magnet stator, and a commutator and brushes that supply power to the excitation coils of the rotor, By providing an intermediate tap in the excitation coil to divide the excitation coil into a first coil and a second coil which are excited to opposite polarities, and by cutting out a part of the conductive part in the commutator, the rotor When rotated by a predetermined angle, one side becomes O.
A first switch and a second switch are formed in the FF so that the other switch is turned on, and the intermediate tap is connected to a power source, and the first switch and the second switch are connected in series to the first coil and the second coil. and the first switch and the second switch are connected to the power source via a changeover switch, and the rotor is configured to rotate forward or reverse by switching the changeover switch. Dynamic rotary actuator.
