Abstract

The available magnetic circuit algorithm is difficult to calculate exactly the electromagnetic torque of the asynchronous magnetic coupling (AMC). The present study establishes the gap flux density theory model by the use of vector magnetic potential method and the two-dimensional field boundary condition, and then analyzes the variation law of induction current among the cage bars along with the spatial phase and electric angle. The Lorenz force is integrated around the circumferential direction, and then the electromagnetic torque model was established according to the current superposition principle. The obtained theoretical gap flux density, cage bars induced current and torque were analyzed comparatively with the finite element method. The revolving speed curve, torque curve and current curve of AMC under rated condition were obtained by the method of finite element dynamic analysis, and then the electromagnetic torque characteristic curve was draw to reveal its dynamic operation law. At last, the correctness of the mechanical characteristics of AMC was verified by experimental results.
