Abstract :
In the present study, a novel small permanent magnet generator is proposed. Various characteristics are analyzed using the FEM. A suitable structure for high power and low cogging torque is investigated. Low-cogging-torque characteristics can be achieved by optimization of the auxiliary pole shape. The proposed generator is a low cogging torque generator that operates at low speeds and so is expected to be useful as a wind generator or a hub dynamo for the bicycle.
