Design of electric motor for e-bike application
Full text linkThis paper focuses on the design of an electric motor for e-bike application. It aims to provide guidelines for choosing and designing electric motors for e-bikes, with a focus on permanent magnet synchronous motors. The analysis combines a preliminary analytical model and finite element analysis simulation to test different motor geometries and verify results with experimental data from commercial motors. The goal is to provide a detailed general procedure for the design of e-ike electric motors and contribute to the development of more eco-friendly mobility
A Guideline for Selecting Motors for Electric Bikes Based on Magnetic Analysis and Measurements
No full textThis article provides an analysis of different traction motors for electric-bicycle (e-bike) applications, focusing on synchronous permanent magnet motors. The study aspire to be a guide for the selection of a proper motor geometry (rotor type, slot/pole ratio, winding configuration) based on the current state of the art. The work includes a comparison of different rotor typologies and winding configurations, carried out through finite element analysis and experimental tests. The article highlights the impact of the motor topology on the performance of the motor drive, and provides recommendations for the design of high-performance PM motors for e-bike applications
Pole-Changing in Synchronous Machines: A Reluctance-Permanent Magnet Hybrid Motor
Full text linkThe change of the number of poles in three-phase electrical machines has always been applied exclusively to induction motors. The main advantage of varying the number of poles in induction motors is the possibility to operate with two different synchronous speeds. This article investigates the possibility to vary the number of poles in synchronous motors as well. A hybrid reluctance-permanent magnets synchronous motor is presented. Its design is described, then the operating principle is illustrated through finite element analysis. Finally, the dual polarity operation for such a synchronous motor is demonstrated through experimental tests on a prototype. The work shows that a dual-polarity synchronous machine can be designed and its operation and capabilities are verified through the prototype characterization
Overload capability test of a permanent magnet synchronous motor for e-bike application
