Abstract:  Using magnetic circuit method to solve the no-load magnetic flux leakage coefficient is not accurate. The change of the rotor extremely logarithm, the permanent magnet thickness, the magnetic set of thickness, the air gap length influence on generator leakage flux and magnetic flux leakage coefficient by the way of finite element method without changing the stator structure of tangential magnetic field PM generator, provided technical support for the design of the angential PM generators.
Key words:  tangential magnetic field; PM generators; magnetic flux leakage analysis
