Slot Servo (Yoke Separation) motor core
The stator adopts the combined structure of tooth and yoke, which greatly reduces the production cost of iron core compared with the conventional segment structure. In the design of the rotor, the magnetic steel structure adopts IPM structure. Compared with the conventional SPM structure, the cost of the magnetic steel is reduced synchronously. Moreover, the stator and rotor punched from one die, and the cost of a set of iron core is reduced by more than 15% compared with the previous scheme.
