A control device of a vehicle, the vehicle includes an engine, a hydraulic clutch disposed on a power transmission path between the engine and driving wheels, a starter motor for use in startup of the engine, an electric oil pump device discharging hydraulic oil generating oil pressure supplied to the clutch, and a power supply device supplying electric power driving each of the starter motor and the electric oil pump device. The control device includes a startup control unit that performs starter startup control of starting discharge of the hydraulic oil by the electric oil pump device after determining that output voltage of the power supply device or input voltage of the electric oil pump device is higher than or equal to a fixed voltage after completion of cranking by the starter motor upon startup of the engine using the starter motor.

Control device of vehicle

This electric motor includes: a brushless motor (); and a control device () that is coupled integrally to an end of a motor case () in an axial direction. The control device () includes: a bus bar unit main body () that has a base unit () with a plurality of bus bars wired thereinside and has a connector unit () provided integrally on the base unit () and led out to an outside of a housing (); a motor drive unit () that drives the brushless motor (); and a motor control unit () that controls the motor drive unit (). The motor drive unit () is attached to a first main surface () of the base unit () while the motor control unit () is attached to a second main surface () of the base unit ().

Electric motor and electric pump

A starter includes a motor unit, a drive shaft configured to receive a rotational force of the motor unit and rotate, a transmission pinion gear installed on the drive shaft, an idle shaft extending in a direction parallel to the drive shaft, an idle gear installed on the idle shaft and configured to mesh with the transmission pinion gear, a driving pinion gear installed on the idle shaft and configured to mesh with a ring gear of an engine, a gear cover configured to rotatably support portions of the drive shaft and the idle shaft and accommodate the transmission pinion gear and the idle gear, and a bracket section installed between the motor unit and the gear cover and configured to rotatably support a first end in an axial direction of the idle shaft.

Starter

A brushless motor according to the present invention is provided with a tubular stator case, a stator core fitted into the stator case, and a rotor rotatably supported via a bearing inside the stator core. The stator core includes a tubular yoke portion and a plurality of split cores which are detachably mounted on the tubular yoke portion. A plurality of commutating-pole teeth which extend radially inward are integrally formed on an inner peripheral surface of the tubular yoke portion at regular intervals in the peripheral direction of the tubular yoke portion; and a root portion of each of the commutating-pole teeth has inclined shoulders which are gradually enlarged radially outward.

Brushless motor

A brushless motor is provided with: a tubular stator case; a stator core; a rotor rotatably supported via a bearing inside the stator core; a bracket which closes an opening at one end of the stator case; a coil bobbin around which a coil is wound is mounted on an inner peripheral surface of the stator core; a lead wire which feeds power to the coil; and a wiring substrate which relays a connection between one end of the lead wire and the coil, wherein: a drawn-out hole is formed on the bracket at the position corresponding to the connection point of said one end of the lead wire and the wiring substrate such that the other end of the lead wire is drawn outward; and a harness guide is provided on a peripheral edge of the drawn-out hole such that the drawn lead wire is bent and fixed.

A brushless motor according to the present invention is provided with: a tubular stator case; a stator core fitted into the stator case; and a rotor rotatably supported via a bearing inside the stator core, wherein: an inner flange portion which extends radially inward is formed at a peripheral edge of an opening of one end of the stator case; and a bracket is fixed to the inner flange portion while contacting therewith so as to close the opening.

A brushless motor according to the present invention is provided with: a tubular stator case; a stator core; and a rotor. The stator core includes a tubular yoke portion and a plurality of split cores. A plurality of dovetail grooves are formed in an inner peripheral surface of the yoke portion; each split core has a coil bobbin which has a mounting hole so as to penetrate in a radial direction, and a split teeth which is mounted into the mounting hole of the coil bobbin. The coil bobbin has a winding portion, and flange portions, and a clearance portion into which a winding starting end of the coil is strayed from the winding portion is formed on the inside of the one of the flange portions by reducing the thickness of the flange portion such that.
