When pulse currents 9, 10 of the waveforms (C), (D) flow from a control section, two couples of forces 11, 12 and 13, 14 are produced in the coils 2, 3 and the revolution is increased. When the current is reversed, the speed is reduced. Then, when the control coils turn by theta deg. and pulse currents 15, 16 delayed by theta deg. from the pulse currents 9, 10 flow, two couples of forces 17, 18 and 19, 20 are caused and the slope of the rotating shaft is changed.
