A motor assembly includes a housing, a first substrate, a second substrate, and a cover. The housing includes a tubular portion that accommodates a motor whose axis of rotation extends in the vertical direction. The first substrate opposes the radial outer end surface of the tubular portion in the radial direction. The second substrate extends perpendicularly to the axial direction and is above the motor. The cover includes a first cover portion that covers the radial outer end surface of the first substrate, and a second cover portion that covers the upper surface of the second substrate. The outer edge of the first cover portion as viewed from the radial direction and the outer edge of the second cover portion as viewed from the axial direction come into contact with the housing via a seal.

The present invention may provide a motor including a shaft, a rotor coupled to the shaft, a stator disposed to correspond to the rotor, and a busbar disposed above the stator, wherein the stator includes a stator core and coils, the busbar includes a busbar body and a plurality of terminals disposed on the busbar body, the terminals include terminal bodies, first protrusions extending from end portions of the terminal bodies and connected to end portions of the coils, and second protrusions branched off from the first protrusions and connected to power terminals, and the plurality of second protrusions are disposed at the same position in radial and vertical directions of the busbar and disposed at equal intervals in a circumferential direction of the busbar.

A rotary motor stator includes a plurality of stator teeth and a plurality of terminal securing blocks. The stator teeth are arranged in a ring to define a rotor accommodation space. Each stator tooth includes an inner side, a winding section and an outer side. The inner side is closer to the rotor accommodation space than the outer side, and the winding section is located between the inner side and the outer side for winding a coil. Each terminal securing block is fixed to the outer side of each stator tooth, and each terminal securing block includes a first wire slot configured to secure an end of the coil. An angle between a line passing through a center of the ring and a center of each terminal securing block and a lengthwise direction of the first wire slot is an acute angle.

The present disclosure relates to a 3-phase connector integrated stator and an electric compressor including the same. The 3-phase connector integrated stator includes: a stator including a plurality of teeth formed to extend from a cylindrical core, insulators coupled to the core and the teeth so as to surround outer sides of the core and the teeth, and coils wound on outer sides of the insulators at the respective teeth; a motor cover coupled to an upper insulator in a central axis direction of the stator and having a connector coupling part protruding upwardly from an upper plate; and a 3-phase connector inserted into and coupled to the connector coupling part of the motor cover and having connection pins connected to 3-phase coils of the stator. Therefore, the 3-phase connector may be easily assembled to the stator, and the connector pins may be easily assembled to the 3-phase connector.

In at least one illustrative embodiment, a power tool may comprise an electric motor comprising a rotor configured to rotate about an axis, a stator assembly including at least three windings arranged around the rotor, and at least three lugs affixed to the stator assembly, where each of the lugs is electrically coupled to one or more of the windings. The lugs may all be arranged to one side of a plane that passes through the axis. The power tool may further comprise at least three electrical wires, where each of the electrical wires is removably coupled to one of the lugs, and a control circuit configured to supply electrical power to the windings, via the electrical wires and the lugs, to drive rotation of the rotor about the axis.

A rotary dynamoelectric machine includes a single- or multi-phase winding system, which is arranged in a stator and has winding connection lines which are guided into a terminal box for contacting external connection lines. The terminal box is located in a region of an end side of the stator, is recessed in a housing of the stator, and is arranged axially between the stator and an end shield.

A capacitor unit (20) includes: a harness side terminal (23) provided in a housing (22) for accommodating a capacitor main body therein and connectable to an electric power harness for supplying DC power from an outside; and a board side terminal (24) connectable to a circuit board from which the DC power is output via the capacitor main body. The board side terminal (24) extends in a plate shape from a base portion (24b) held in the housing (22) toward a distal end portion (24a) connected to the circuit board, and has a notch portion (40) recessed inward of the board side terminal (24) in a width direction between the base portion (24b) and the distal end portion (24a).

The present disclosure discloses an electric assembly and a vehicle having the same. The electric assembly includes: a box assembly; a motor, disposed in the box assembly; a transmission, disposed in the box assembly, where the transmission is power-coupled to the motor; and a controller, disposed outside the box assembly, and fixedly connected to the box assembly.

A rotary actuator is used in a shift-by-wire system for a vehicle. The actuator includes a motor, a controller, a housing, and a bus bar. The controller controls the motor. The housing holds a stator of the motor and the controller. The bus bar includes a terminal and a holder. The terminal electrically connects a coil of the stator to a control board of the controller. The holder is molded with a part of the terminal. The terminal includes a board-side arm that extends from the holder and a connecting pin that protrudes from the board-side arm toward the control board and that is connected to the control board. The board-side arm includes a stress releasing member that extends along an imaginary plane in parallel with the control board. The stress releasing member includes at least one curved portion at which the stress releasing member is curved or bent.

A rotating electrical machine is equipped with a rotor and a stator. The rotor includes a magnet unit and a rotor core retaining the magnet unit. The rotor core is made of a stack of annular core plates and an annular end plate mounted on an end of the stack of the core plates. The end plate has a deformable wave shape. The stack of the core plates and the end plate has formed therein through-holes extending through a length thereof. Bar-shaped fastening members, such as rivets, which have flanges on ends thereof are inserted into the through-holes with the flanges pressing the end plate to elastically deform the wave shape of the end plate, thereby tightly gripping the stack of the core plates in the lengthwise direction. This minimizes concentration of stress on the core plates to eliminate a risk of damage or breakage of the rotor.
