An electric machine stator includes a soft magnetic yoke having a cylindrical yoke body extending along a central axis, with an outer surface and an inner periphery defining a central opening about the central axis, and a plurality of soft magnetic stator teeth. Each stator tooth defines a first set of air pockets, and a second set of air pockets. An electric machine rotor and permanent magnet material with air pockets are also provided.

A motor and an assembling method of a motor rotor structure are disclosed. The motor includes a stator, a rotor, an insulating assembly, and a shaft. The rotor includes a main body and magnetic members. The main body has an outer surface, a channel and two end surfaces. The channel runs through the two end surfaces so the main body is in a shape of annular column. The end surfaces are connected to the outer surface. The magnetic members are disposed on the outer surface. The insulating assembly is connected to the end surfaces. The insulating assembly has positioning portions. Each magnetic member is located between two adjacent positioning portions, and the magnetic members can be positioned on the outer surface through the positioning portions. The shaft passes through the insulating assembly and the channel, and connects to the main body through the insulating assembly.

A high-frequency high-speed swing motor and a method for implementing same. The motor comprises a housing (9); an end cover (1) is embedded at one end of the housing; a stator assembly is connected to the inner wall of the housing; a rotor assembly is provided inside the stator assembly; the stator assembly comprises coils (5), an iron core (10), and a stator magnetic steel assembly; the iron core is embedded inside the housing; the stator magnetic steel assembly is disposed inside the iron core; the coils are also wound inside the iron core; the rotor assembly comprises an output shaft (8) and a rotor magnetic steel assembly; the two ends of the output shaft are respectively rotatably connected to the housing and the end cover.
