Development of Power-Assist Device for a Manual Wheelchair Using Cycloidal Reducer

This paper presents the design process and driving performance test results of a power-assist module to which cycloidal reducer is applied in order convert manual wheelchair into an electric wheelchair. The types electrification modules currently used electrify wheelchairs include front-mounted, rear-mounted, powered wheels. These assist devices are either difficult carry transport independently or require excellent hand dexterity operate. To overcome this problem, with no pin roller, novel curve were designed develop small easy-to-handle that was tested by installing As result test, maximum speed 6 km/h, slope can climb 20%, 0.358 Ah consumed while moved 360 m current consumption test. showed it possible small-sized module. In addition, user easily adding weight without replacing wheel. consists DC servo motor, reducer, battery, joystick.
