A stator that includes an annular stator core having a plurality of slots each having a coil insertion opening that opens in a radial direction, and recesses formed in circumferential side walls and extending in an axial direction; a coil including slot accommodated portions accommodated in the plurality of slots; and a wedge containing a thermoplastic resin and engaged with the recesses so as to close at least a part of the coil insertion opening as viewed in the radial direction of the stator core.

A stator assembly and stator for a motor is provided that directly installs in a conductor slot a slot wedge having a width approximately the same as the width of the conductor slot. The slot wedge is limited in three directions, circumferential, radial, and axial, by means of cooperation between a slot wedge pressing ring, a conductor, and a sidewall of the conductor slot, and at the same time, the slot wedge is capable of preventing the conductor from falling out of the conductor slot. In addition, in the stator assembly for a motor disclosed, when the slot wedge is installed, the slot wedge may not only be inserted and installed in the conductor slot along the axial direction, but may also be inserted and installed in the conductor slot along the radial direction, and thus, the installation mode is flexible, which may improve the installation efficiency.

A synchronous reluctance motor includes a shaft, a rotor, a stator, and multiple magnetic wedges. The stator radially opposes the rotor with a space therebetween. The stator includes a stator core having multiple slots arranged in the circumferential direction and open toward the rotor, and multiple stator coils disposed in the multiple slots. Multiple magnetic wedges close at least some of the multiple slots with the multiple stator coils disposed therein.

A stator including a ring having teeth and slots between said teeth that open radially outwards and material bridges, each linking two adjacent teeth to the respective base on the side of the air-gap, a yoke attached to the ring, and windings placed in the slots of the ring, at least some of the material bridges having at least on deformable zone that can be deformed during assembly of the yoke on the ring.

An electric machine may include an stator and a rotatable rotor. At least one of the stator or the rotor may include a plurality of multi-part trapezoidal teeth with an electromagnetic coil disposed around each tooth.

A motor stator structure includes a main body and multiple stopper plates. The main body has multiple magnetic poles and a shaft hole. The magnetic poles outward extend from the main body. Each magnetic pole has a free end outward extending from the main body. The shaft hole passes through the main body between two ends thereof. The stopper plates are respectively correspondingly assembled with the free ends of the magnetic poles. In the motor stator structure, the windings are more densely wound on the magnetic poles to enhance the magnetization efficiency.
