摘要：
PURPOSE: A motor assembly for electromotive wheel chairs is provided to offer a motor assembly as being embedded in driving wheels in a compact size in order to increase operability of the electromotive wheel chairs by offering simplicity of operation by reducing total weight and volume. CONSTITUTION: A motor assembly for an electromotive wheel chair (115) comprises left and right frames which include seats in the center and front and a back of a chair and a handle in the back； a driving wheel (107) which is installed with a driving tool for generating power in both rear sides of the left and right frames； assisting wheels installed in front of the driving wheel； arm rests installed in both sides of center of the left and right frames and foot rests installed in front of the left and right frames； and a controller which controls driving wheels by installing in the arm rests. The motor assembly comprises a cylinder shaped motor housing (116)； a stator (117) and a rotor (118) which are installed to generate rotary power by being applied power from a battery inside the motor housing； a rotation shaft (119) which is installed in the rotor and is protruding towards inner direction of the motor housing； a motor cover (121) which finishes by embedding a slowdown tool inside the motor housing； an output shaft (126) which is installed to connect the slowdown tool to the outer end of the rotary shaft and to receive the slowed power to the outer side of the slowdown tool； and a driving wheel socket which connects the output shaft to the wheels and helps driving by delivering power to the driving wheels. The motor assembly has an in-wheel type in which the whole motor housing is covered by the wheels.본 발명은 부피와 무게를 최소화하여 작동의 용이성을 제공하면서 원가를 절감하고 주행소음을 배제하여 쾌적한 승차감을 제공하고 전력소모를 줄일 수 있도록 한 것으로서, 전동휠체어를 구성하는 구동륜에 장착되는 모터 어셈블리를 구성함에 있어서；상기 모터 어셈블리는, 원통 형상으로 구비되는 모터하우징과, 상기 모터하우징 내부에 배터리로부터 전원을 인가받아 회전력을 발생시키도록 설치하는 고정자와 회전자, 상기 회전자에 설치하여 모터하우징의 내측 방향으로 돌출되는 회전샤프트, 상기 모터하우징의 내부에 감속수단
