Embodiment Construction
[0020] The present invention will be specifically described below by taking a three-phase motor used in an electric vehicle as an example.
[0021] see Figure 1-2 , the present invention includes a motor 1, a microprocessor 2, a control circuit and a storage and supply circuit, the control circuit includes a signal detection circuit A3, a transformer 4 and a converter 5, and is equipped with a reversing switch 6 and a shift switch 7. The signal detection circuit A3 is used to collect the input / output voltage and current signals of the stator side of the motor; the transformer 4 is used to perform step-down / boost processing on the electric energy delivered by the converter to the motor when the system is in a driving state, and to When the system is in the braking state, the electric energy delivered by the motor to the converter is raised / lowered; the converter 5 is used to regulate the driving / braking state of the system and realize the AC-DC conversion of the delivered elec...
