Abstract
PURPOSE:To provide high performance under simple constitution by detecting power generation voltage generated at 2-phase coil and controlling in such manner that drive voltage detecting section's signal may become a value corresponding to power generation voltage signal, and thus the electric current at current switching means is controlled. CONSTITUTION:Rotor 1 containing field having N pole, S pole and nonmagnetic pole, and stator 7 containing 2-phase coils 8, 9 interlinking with magnetic flux generated by the field section, constitute an electric motor. In addition, switchover section 14 which changes current path to 2-phase coils 8, 9 by means of Hall element 10 detecting the relative position of rotor 1 and stator 7, is provided. At the same time, generated power voltage detecting section 12 and drive voltage detecting section 13 of 2-phase coils 8, 9 are provided. Their signal is inputted to current control section 11, to control current on current circulation switching section 14. Consequently, it is possible to minimize the number of phases under simple constitution and at the same time, to provide high performance by detecting power generation voltage of coils.
