Design of a mutually coupled external-rotor direct drive E-bike switched reluctance motor

In this paper, a concentrated-wound exterior-rotor direct-drive electric bicycle (e-bike) mutually coupled switched reluctance motor (MCSRM) has been designed to match the performance parameters and dimensional constraints of a commercially available permanent magnet e-bike motor. Different stator a...

description In this paper, a concentrated-wound exterior-rotor direct-drive electric bicycle (e-bike) mutually coupled switched reluctance motor (MCSRM) has been designed to match the performance parameters and dimensional constraints of a commercially available permanent magnet e-bike motor. Different stator and rotor pole configurations are compared for a 3-phase MCSRM. During the design process, many parameters have been evaluated and analysed. The finalised performance capabilities of all pole configurations are summarised, and the choice of pole configuration for the final design is justified. The full dynamic torque-speed performance of the finalised 15/10 MCSRM is presented, along with a detailed thermal analysis. Finally, the MCSRM performance is compared to a 12/16 non-coupled SRM and a commercially available permanent magnet motor.
