Abstract: The special magnetic circuit of coreless motor with ring magnet was analyzed, and the magnetic circuit model was given. The analytical expression of no-load leakage coefficient was listed according to the model, and was calculated for two types of motors with different outer diameters. The calculated results were consistent with those of magnetic field line method and vector magnetic potential method, which verified the accuracy of the analytical expression. The establishment of the analytical expression of no-load leakage coefficient of coreless motor with ring magnet provided basis for magnetic circuit calculation of coreless motor with ring magnet.

Key words: coreless motor, ring magnet, leakage coefficient
