Abstract
This thesis proposes a novel design of a dedicated rim motor for electric wheelchairs. This rim motor consists of a rotor and two sectors of stator on each wheel. The rotor is an assembly of magnets plugged in the tube of rim, while the stator is 45 degree fan-shape plate.
Before the design of rim motor, it is necessary to analyze the specifications of the electric wheelchair.A 2D magnetic model of the rim motor is created to perform the optimal design by the use of the optimizer Multi-Object System Tool(MOST). The Optimal results are verified and refined by 3D Finite-Element Analysis (FEMA) electromagnetic analysis software.The prototype of rim motor is fabricated and tested on dynamometer. The experiments show that the back emf constant is 4.5rpm/volt and the torque constant is 0.26 kgm/amp.
