A stator () according to the present invention comprises: a yoke part () composed of a plurality of block bodies having an arc shape with a rectangular cross section; fixing members () for disposing and fixing the plurality of block bodies in an annular shape; a plurality of teeth parts () erected on the peripheral surface of the yoke part; and a coil () wound around the plurality of teeth parts ().

Stator and motor including the stator

A resonant motor system having a resonant circuit that includes magnetic coils and of capacitors, for generating an electric power when the resonant lot is rotated by an engine, a regenerating portion for the resonant motor, a motor driving portion, a motor control portion, and a capacitor portion for storing therein the electric power generated by the resonant motor when the resonant motor is regenerated, the resonant rotor being driven by the electric power stored in the capacitor portion when the engine is assisted by the resonant motor.

Resonant motor system

An electromagnetic type retarder comprises a main portion consisting of a stator having a plurality of magnetic coils arranged along a circle and spaced apart from one another, and of a steel rotor surrounding the stator and rotated according to the rotation of a tire; a driving device for the main portion to be controlled by an operation signal; and an output terminal for an additional device; the magnetic coils consisting of three-phase or two-phase connections. Each of the magnetic coils is connected with a capacitor so as to form a resonance circuit, respectively. The driving device has transistors connected in series to each of the connections and controlled so as to be opened and closed by the operation signal. The revolution speed of a rotary magnetic field generated by AC voltage induced in the magnetic coils forming the resonance circuits by the rotation of the steel rotor is set smaller than the revolution speed of the steel rotor. The AC voltage is applied to an input terminal of the additional device through a timer after a predetermined time from the generation of the operation signal.
