[0072] Implementation case:
[0073] The stator transmitting coil 7 and the receiving coil 5 are connected together, and fixed on the stationary rotating shaft, and the rotor reflection coil 6 is fixed on the rotor of the motor, and the three are coaxially and parallelly fixed and placed to complete the equipment construction work;
[0074] The front-end power supply module performs alternating current excitation on the stator transmitting coil 7. Since the stator transmitting coil 7 is in the shape of a mosquito coil, an alternating magnetic field will be generated in its axial direction.
[0075] According to the electromagnetic induction theorem, the axial alternating magnetic field generated by the stator transmitting coil 7 will excite the receiving coil 5 and the rotor reflecting coil 6 to generate alternating current. Due to the special design of the receiving coil 5, the effective magnetic flux area of the sin receiving coarse adjusting coil 2, cos receiving coarse a...
