Abstract

In this paper, the high-performance electric motor is designed for electrified bikes. High power density at low speeds is one of the challenging steps in e-bikes. Desired features from the electric motor are discussed and the required parameters such as outer diameter, stack length, operating speed, and torque are determined. Then step-by-step design study is executed. Spoke IPM design tips are mentioned and related analyses are performed through finite element analysis. The results show that developed spoke-type IPM in the limited volume can run the bike efficiently and silently which are the signs of successful design.
