The present specification discloses a motor assembly. An embodiment of the motor assembly disclosed in the present specification may comprise: a motor housing in which a motor is received; a shaft which forms the rotation axis of the motor; a rotor which is coupled to the shaft; a plurality of cores and coils which are provided along the circumference of the rotor to form a flux path; and insulators which are coupled to the cores to insulate the cores from the coils, wherein each of the insulators may comprise an insulating portion which covers the outer surface of the corresponding core and a fixing portion which protrudes outward from the insulating portion in the radial direction of the rotor, and the fixing portion may be coupled to the inner circumferential surface of the motor housing.

An insulator according to an embodiment includes a teeth cover portion and a crossover-wire guide portion. The crossover-wire guide portion includes a plurality of guide walls, a drawing groove, a drawing path, and a crossover-wire support portion. The plurality of the guide walls separate the crossover-wire portions of the coils and are capable of guiding the crossover-wire portions in the core circumferential direction. The drawing groove penetrates through all of the plurality of the guide walls in the core radial direction. The drawing path is disposed at a position away from the drawing groove in the core circumferential direction. The crossover-wire support portion changes a direction of the crossover-wire portion of the coil drawn out from the drawing groove, to be directed to the drawing path, and supports the crossover-wire portion.

An iron core assembly, a motor, a compressor and a vehicle are provided. The iron core assembly has an iron core body and multiple insulating skeletons. The iron core body has multiple iron core blocks. A mounting groove is provided at an edge of at least one end face of each iron core block. Each iron core block is arranged between two insulating skeletons. Out of the two insulating skeletons provided at two ends of an iron core block, an end face of at least one insulating skeleton, facing the iron core block, is provided with insulating protrusions. The insulating protrusions can wrap two sides of the iron core block. The insulating protrusions match the mounting groove.

Provided is a motor which includes a stator including a stator core, a coil wound around the stator core, and an insulator mounted on the stator core and configured to insulate the coil and the stator core, a busbar disposed on the stator and conductively connected to the coil, a rotor disposed inside the stator, and a shaft coupled to the rotor, wherein the insulator includes a vibration prevention unit which extends from an upper side of an inner circumferential part and is in contact with an inner circumferential surface of the busbar. Therefore, the motor prevents a coating of a coil from being worn or cut by preventing the busbar from moving without an additional process or component.

A resolver has a lead wire that can be slack even in a structure in which it is impossible to maintain the distance between an end of wound wire and a terminal pin without using a special jig. A lead wire of a stator coil 500 is entwined on a plurality of terminal pins 603 in a slack condition, and the entwined parts are fixed by soldering or welding. Terminal base 600 is then moved to a stator core 200 side, and the lead wire is made slack by contacting the lower surface of a terminal base body 601 to the upper surface of the stator core 200. Next, end part of the pins 306 of a primary insulator 300 are melted so as to fix the terminal base 600.

Disclosed is a stator of a motor including a stator core manufactured by a plurality of steel sheets laminated on top of each other; an upper insulator which covers the upper parts of the core base and the teeth to insulate them; a lower insulator which covers the lower parts of the core base and the teeth to insulate them; a coil which is wound on the teeth covered and insulated by the upper insulator and the lower insulator and is connected between the neighboring teeth; and a coil protection cover which covers an upper part of the connected part of the coil to prevent the coil connected between the neighboring teeth from being exposed to the outside.

To provide a stator of a motor having an insulating structure achieving insulation easily and reliably. A stator (1) of a motor comprises: a teeth unit (11) with a circular cylindrical part (111) having a circular cylindrical shape and multiple projection parts (112) spaced uniformly along an outer circumference of the circular cylindrical part (111) in a circumferential direction of the circular cylindrical part (111), the projection parts (112) projecting radially outwardly from the circular cylindrical part (111); multiple bobbins (13) having cylindrical shapes with hollow sections (133) through which the projection parts (112) of the teeth unit (11) are passed to be fitted in the hollow sections (133), the bobbins (13) having outer peripheries around which windings (14) are wound; a cylindrical external unit (12) arranged radially outside the teeth unit (11) and fitted to an outer circumference of the teeth unit (11) and the outer peripheries of the bobbins (13); and multiple first insulating parts (15) arranged to fill gaps between the circular cylindrical part (111) of the teeth unit (11) and the bobbins (13) and electrically insulating the teeth unit (11) and the windings (14).
