The invention discloses a high-speed high-
power density AC
servo motor, which belongs to the technical field of motors. The high-speed high-
power density AC
servo motor comprises a
stator part and a rotor part, wherein the
stator part comprises a frame, a
stator iron core, stator windings, end covers and bearings; the rotor part comprises a rotation shaft, rotor magnetizers, permanent magnets and a stainless steel band; two ends of the frame are provided with the front end cover and the rear end cover; the frame is internally provided with the rotation shaft, the stator iron core, the stator windings and the rotor part; the rotor magnetizers sleeve the rotation shaft, the tile-shaped permanent magnets are
adhesive to the outer surface, and an air gap
magnetic field is generated; cast aluminum
alloy is adopted to cast the frame, the front end cover and the rear end cover, and thermal
processing is carried out;
silicon steel sheets are adopted to process the stator iron core, and the
oxide layer on the surface of the
silicon steel sheet serves as inter-sheet insulation; the inner circle of the iron core ring is uniformly provided with grooves parallel with the axis, the stator windings are embedded in the grooves, and each stator winding adopts a high temperature-resisting
copper wire; the rotor part is assembled; and the stator part and the rotor part are combined together. The rotation speed of the motor is high, the
power density is large, and the operation is steady.
