Dynamic Characteristics Analysis and Calculation of Adaptive PowerMotor Based on Speed Coupling

Adaptive power motor is a new type of driving motor, which is suitable for urban heavy load electric vehicle, and has the characteristics of speed coupling. For a 6 poles adaptive power motor, the design principle and the suitable operating mode were described. By using electromagnetic theory and motor learning theory knowledge,the power output performance of the adaptive power motor was analyzed and calculated, concluding that the reduced turn working condition under the same speed could save more electric energy on the vehicle, which was verified by the simulation analysis software. At the same time, the results showed that, compared with the full turn working state, the mechanical characteristics of the adaptive power motor operating in the state of reduced turn was more hard. Finally, the correctness of the theoretical calculation and the simulation analysis was proved by the prototype test, which proved that the design model of the motor was feasible.
