Abstract

Abstract:

To ensure that the rotor core of automotive permanent magnet synchronous motor （PMSM） has the ability to withstand large peeling forces， while avoiding destructive peeling test， two stacking processes， i.e. stacked riveting and adhesive process are modeled based on the principle of force-energy equivalence and the bilinear cohesion model introduced， with the peeling forces of rotor core obtained through simulation in this paper. Firstly， a peeling test platform for motor rotor core is constructed to compare the maximum peeling force of two stacking processes by test. Then the no-load radial magnetic density of PMSM under two processes is analyzed by simulation with ANASY Maxwell. The results show that the adhesive process adopted can greatly enhance the peel strength of the iron core， and meanwhile increase the operation efficiency of motor and the closeness of air-gap magnetic field to sine function， and reduce the operating current and losses of motor.

Key words: rotor core, cohesion, force-energy equivalence, peel strength, radial magnetic density
