Motor-driven system with stator provided with inductors

摘要: There is provided a motor-driven system which realizes an optimum driving mode for electric automobile, robot carrier car, drum of copying machine, etc., and having function as actuator such driving. In rotational machine with stator outer rotor type permanent magnet rotor, the annular magnetic substance, main poles so to extend radially outward from windings wound on respectively, inductors each constituted by plurality teeth formed at forward end corresponding one poles, north (N) south (S) arranged alternately inner circumference in rotating direction being opposition other while air gap held therebetween, there body tire, drum, table or like mounted circumferential portion side rotor.
