Non-bearing switch reluctance motor complete-period electrification operating control method

The invention relates to a bear-free switch magnetic resistance motor complete period generating operation control method, belonging to the generation technology of the bear-free switch magnetic resistance motor. In the method, the suspension coil on each of the stator tooth pole is controlled independently, and the main coil connected in series on the stator tooth pole composes the complete period generation coil. Through controlling the different current of the opposite two suspension coils radially, the air gap field built by the two suspension coils is unbalanced, to generate the asymmetric radial magnetic pull. While the suspension coil current used as the generated exciting current provides the excitation energy to the main coil in the complete period, wherein the main coil outputs the electric energy to provide to the load after rectifying as the generating coil, which realizes the complete period generation of the bear-free switch magnetic resistance motor, effectively advances the availability of the suspension coil and the power density of the bear-free switch magnetic resistance motor, settles the basis for the application of the high speed generating field with high power density request.
