Abstract

The invention provides a design method of a vehicle permanent-magnet synchronous motor. According to the design method, a motor structure parameter such as a stator inner diameter, a rotor outer diameter, an air gap length and an armature calculation length can be determined according to actual performance of a permanent-magnet synchronous motor, the output performance of the permanent-magnet synchronous motor also can be simulated and analyzed by a computer simulation method, the motor structure parameter determined by the method is analyzed and verified, the probability that aspects such asperformance output quantity, dynamic characteristic and working efficiency of an experiment sample do not conform to design requirement is reduced, so that the design cost of the permanent-magnet synchronous motor is reduced, and the design period is reduced.

Description

technical field [0001] The invention relates to the technical field of motor design, in particular to a design method of a permanent magnet synchronous motor for vehicles. Background technique [0002] The motor is the core component of the power system of a new energy vehicle. While fully satisfying the performance of the vehicle, it should also satisfy the comfort during driving, environmental adaptability and the mileage of a single charge. Correspondingly, the motor for a vehicle Compared with ordinary industrial motors, the design of the motor has stricter technical specifications. [0003] Traditional permanent magnet synchronous motor design theory and analysis methods mainly include analytical magnetic circuit analysis method and finite element method. The analytical magnetic circuit analysis method is based on the classical mathematical analysis method to obtain the relational expression between the motor performance and the design parameters, which is a fast and e...
