A brushless motor comprising: a rotor; a stator core disposed at a radial direction outside of the rotor, and a stator case. The stator core includes an outer ring shaped section, teeth sections projecting out from the outer ring shaped section toward a radial direction inside, and an inner ring shaped section extending from end portions of the teeth sections. Protruding portions are formed at the outer ring shaped section so as to project toward a radial direction outside and so as to be disposed at even intervals around a circumferential direction of the outer ring shaped section. The stator case is integrated together with the stator core by a plurality of plastic deformation portions formed at an outer peripheral portion of the stator case at locations facing towards the protruding portions, and the plastic deformation portions are disposed at even intervals along a circumferential direction of the stator case.

Brushless motor, stator, stator manufacturing method and brushless motor manufacturing method

An electric pump includes a motor rotor provided in a first end region in the axial direction of a rotary shaft, a pump rotor provided in a second end region in the axial direction of the rotary shaft, and a pump housing supporting the rotary shaft. The pump housing has a first housing portion for accommodating the pump rotor and a second housing portion having a blocking portion. The first housing portion has a suction port for drawing in fluid and a discharge port for discharging the drawn-in fluid.

Electric pump

A metal pump housing includes a shaft support hole for supporting a middle part of a rotary shaft. The rotary shaft includes a first end on which a pump operating portion is provided and a second end on which a motor rotor is provided. A metal motor case is fixed to a part of the pump housing that is at a side of the second end. The motor case accommodates a motor section including a motor stator and a motor rotor. A plastic circuit case member is fixed to a part of the motor case that is opposite to the part to which the pump housing is fixed. A circuit substrate for controlling the motor section is fixed to the circuit case member and is separate from the motor case.

Electric pump having plastic circuit housing

A motor includes a motor body, a pin, a core, and an input cam. The motor body includes a housing and an output shaft. The pin is arranged in the output shaft to extend in a direction orthogonal to a rotation axis of the output shaft. The core is pivotally supported by the pin and rotates coaxially with the output shaft. The input cam is annular and surrounds an outer circumference of the core. The input cam rotates integrally with the core. An end surface of the core closer to the housing includes a first deviated surface. The core includes an insertion portion into which the pin is inserted. When a center axis of the core is coaxial to the rotation axis of the output shaft, the first deviated surface is located at a position farther from the housing than the insertion portion.

Motor

An electric oil pump is coupled to a pump receptacle including an oil inflow passage and an oil outflow passage. The electric oil pump includes a motor, a pump rotor, a housing, and a check valve. The housing accommodates the motor and the pump rotor. The housing closes an opening of the pump receptacle and includes at least a fitted portion fitted into the pump receptacle. An oil compartment is formed between the pump receptacle and the housing. Oil flows into the oil compartment from the oil inflow passage when the pump rotor is rotated. The fitted portion is partially immersed in the oil collected in the oil compartment. The housing includes a suction port and a discharge port. A check valve, located in the housing, limits reversed flow of the oil from the oil compartment to the oil inflow passage.

Electric oil pump and hydraulic pressure supply device

In a drive force transmission apparatus, when an input shaft is rotated in a normal rotational direction, a rotational force of the input shaft is transmitted to an output shaft through a one-way clutch to rotate the output shaft at a rotational speed, which is the same as a rotational speed of the input shaft. At this time, an input side sub-shaft is freed from an output side sub-shaft. In contrast, when the input shaft is rotated in a reverse rotational direction, the rotational force of the input shaft is transmitted to the output shaft through an input gear, a first gear, the input side sub-shaft, a two-way clutch, the output side sub-shaft, a second gear and an output gear. At this time, the output shaft is freed from an intermediate shaft.
