A method for producing a stator assembly of an electric motor includes: providing a laminated core of the stator assembly; mounting at least one coil former on the laminated core; mounting a ground contact pin on the laminated core provided with the coil former; and overmolding the laminated core with plastic.

A stator is configured so as to have an annular shape by linking core blocks that are each produced by laminating electromagnetic steel sheets and that each have a yoke portion and a tooth portion by bendable first linking portion, concentrated winding coils are each produced by winding a conductor wire around the tooth portion for a number of turns so as to pass through concave spaces that are formed by the trunk portions and first and second guiding portions of first and second insulating bobbins, and current-carrying member holding portions that hold first current-carrying members that configure the concentrated winding coils into alternating-current connections are constituted by holding grooves that are each formed so as to open radially outward and so as to pass through the first guiding portions circumferentially, and that are arranged in three layers in an axial direction.

A rotating electrical machine connection component includes a plurality of linear conductors, and a first molded resin portion that covers portions of the plurality of linear conductors and connects the plurality of linear conductors to each other. Each of the plurality of linear conductors includes a first straight portion extending out of the first molded resin portion in a direction parallel to a rotational axis of the rotor and connected to the terminal block, a second straight portion extending out of the first molded resin portion in a different direction from the first straight portion and a bent portion bent between the first and second straight portions. Of each of the plurality of linear conductors, a part of the first straight portion, the bend portion and a part of the second straight portion are covered by the first molded resin portion.

A fixture for fixing, to a motor case, a holding jig configured to hold a plurality of power lines connected to respective stator coils so as to restrict a relative movement between the plurality of power lines includes: a fastening hole through which a bolt for fastening the fixture to a motor case is inserted; and a mounting portion on which the holding jig holding the power lines is mountable. The mounting portion includes: an accommodation space in which to accommodate the holding jig; and holding pawls for sandwiching the holding jig.

A disclosed terminal block assembly for a generator includes a terminal block with a base with first and second transverse terminal surfaces adjoining one another. One of the terminal surfaces includes an increased width greater than a length of a cable terminal lug for providing a lightning strike and creepage barrier. The terminal surfaces include spaced apart protrusions extending from the first and second surfaces to provide spaced apart terminal areas overlapping the first and second surfaces. First and second terminal studs are disposed within each corresponding first and second terminal areas and are electrically connected by a bus bar.

A terminal temporary holding structure includes: winding terminals each including a winding-side spot-welded portion having a flat plate shape; a terminal holding base that holds the winding terminals; and cable terminals each including a cable-side spot-welded portion having a flat plate shape and respectively connected with external cables. The cable terminals are temporarily held by the terminal holding base in such a manner that the winding-side spot-welded portion and the cable-side spot-welded portion are opposed to each other, so as to weld the cable-side spot-welded portion of each cable terminal to the winding-side spot-welded portion of each winding terminal. The cable terminals are temporarily held by the terminal holding base at at least two locations that sandwich the cable-side spot-welded portion.

The motor unit includes a motor case containing a stator and a rotor fixed to an output shaft; the control unit includes a unit case containing constituent members of the control unit that controls the motor unit; the motor unit and the control unit are fixed to each other in such a way that an axle-direction end, at the unit case side, of the motor case is made to abut on an axle-direction end, at the motor unit side, of the unit case and then the both ends are bonded to each other.

A gearbox includes: a gearbox main body made of resin that constitutes a part of a speed reducer to which a motor is mounted; and a terminal that conducts power supplied from an external source to the motor. The gearbox main body includes a through hole formed to correspond to a mold that is used to maintain a position of the terminal while the terminal is being integrated with the gearbox main body by insert molding. The through hole may function as a vent hole in the gearbox main body.

Provided are a motor, a scroll compressor, and a processing method of a motor. The motor includes: a stator provided with a plurality of stator slots, a toothed portion being formed between any two adjacent stator slots among the plurality of stator slots, and an aluminum coil being wound in the stator slots and/or around the toothed portions to form a winding, wherein the winding includes a first connecting portion; and a lead wire, which is a copper wire and has an end portion, the end portion being connected to the first connecting portion via a first crimp terminal so as to connect the winding to an external power supply, wherein the first crimp terminal wraps and presses the end portion and the first connecting portion in an axial direction of the lead wire, and a space defined by the first crimp terminal is filled with a tin material. In the present application, the coil forming the winding in the motor is provided as an aluminum coil, and the first connecting portion of the winding and the end portion of the lead wire are crimped together by means of the first crimp terminal, and then the first crimp terminal is filled with the tin material, such that the connection between the winding and the lead wire can carry a large current, and thus the power of the motor is increased while the cost of the motor is reduced.
