PROJECT TITLE :
Design and integration of dual power wheels with rim motors for a powered wheelchair
ABSTRACT :
This study presents the look and integration of dual power wheels for a completely unique powered wheelchair driven by rim motors. Each power wheel is composed of an influence train of a rim motor, drive, hybrid electromagnetic brake and battery bank. The installation of twin power wheels turns a manual foldable wheelchair into a powered wheelchair. The multifunctional optimisation design of two critical elements, the rim motor and hybrid electromagnetic brake, is first introduced. A driving strategy is then proposed for the wheelchair with a stable soft-beginning control, dual-wheel differential speed management, 3-part short-circuit brake management and magnetic particle brake control. The experimental results show that the novel powered wheelchair has higher power economy than most business products in terms of driving vary.
