技術說明

一種高扭力、低轉速手輪馬達驅動機構的新發明，將輪椅的手扶圈與馬達轉子設計合而為一，設計構想的激發起因於手動扶圈動力來自手臂，如果手臂的力量換成電磁力，仍可驅動輪椅行進，因此將手扶圈設計成馬達的轉子，藉手扶圈到輪軸較大的旋轉力臂，可以得到較大的力矩輸出。 This invention relates to a powered wheel for a vehicle such as a wheelchair, an electrical bicycle, or a motorcycle, especially to a vehicle which has a wheel driven by power but without using an independent electric motor. One successful application has been used as rim motors for electric wheelchairs, where the conventional push-rim is used as a motor on each wheel. The rotor of the rim motor is a conventional hand rim plugged inside its tube with a series of magnets of alternate N and S poles. Two sectors of arc stator are designed facing the inner side of the rim. This configuration enables a larger force arm that multiplies the force exerted along the rim to produce a larger torque than the conventional hub-in motor of smaller radius. This dedicated rim motor provides a promising and revolutionary product for electric powered wheelchairs.
