Abstract
A motor, may include a rotor having a shaft which has its center on a center axis extending in one direction; a stator which surrounds the rotor in the axial circumference, and includes a plurality of coils; and bus bars connecting coil ends extending from the coils. The bus bars may include a plate shape member bent in a thickness direction, a width direction of the bus bars being identical to an axial direction of the motor. Each of the bus bars may include a main body portion, and a coil end connection portion which extends from the main body portion and grips one of the coil ends at an opening that is open toward one direction within a plane perpendicular to the axial direction.
Claims11
A motor, comprising:
- a rotor having a shaft which has its center on a center axis extending in one direction;
- a stator which surrounds the rotor in the axial circumference, and has a plurality of coils;
- and
- bus bars connecting coil ends extending from the coils,
- wherein the bus bars are formed of a plate shape member bent in a thickness direction, a width direction of the bus bars being identical to an axial direction of the motor, and
- each of the bus bars has a main body portion, and a coil end connection portion which extends from the main body portion and grips one of the coil ends at an opening that is open toward one direction within a plane perpendicular to the axial direction,
- a bus bar holder which supports the bus bar,
- the main body portion of the bus bar is supported by being sandwiched between a pair of bus bar fixing pieces of the bus bar holder in a thickness direction,
- the bus bar fixing piece has a axially extending rib, and
- among the pair of bus bar fixing pieces, the rib is provided at least to one bus bar fixing piece that is disposed on an opposite side from a direction in which the coil end connection portion of the bus bar is extended.
