Double-rotor iron-core-free permanent-magnet synchronous motor

The invention discloses a double-rotor iron-core-free permanent-magnetic synchronous motor. The problems that an existing motor is large in size, high in weight, low in space utilization rate, and low in loss, in particular the problems of low operation speed, low precision and the like are mainly solved. The double-rotor iron-core-free permanent-magnetic synchronous motor is mainly composed of a stator component and a rotor component, the stator component is annular and is composed of stator winding, and the rotor component is arranged on the outer side of the rotor component in a cup shape in a sleeved mode. The double-rotor iron-core-free permanent-magnet synchronous motor is characterized in that the stator winding is not provided with an iron core, a slot effect does not exist, and low-speed smooth operation is achieved.
