Abstract
A coreless permanent motor has a stator and a rotor rotatably mounted to the stator. One of the stator or the rotor has at least one winding disc (). The other one of the stator or the rotor has at least one surface charged magnet disc (). The winding disc () or the magnet disc () is formed by two or more sector shaped units that are mounted to two or more support members () respectively. The winding disc () or the magnet disc () is formed by closing the support member () and the closed support members () form a cylindrical housing. Thus, the structure of the coreless motor is simplified.
