The present invention provides an electric power unit that is mounted on a mounting object, comprising a motor; and electrical equipment for driving the motor, wherein the motor has a first attachment portion that is attached to the mounting object, and a second attachment portion to which the electrical equipment is attached.

Electric power unit and working machine

An electric power unit includes: a rotary electric machine unit an electrical unit disposed above the rotary electric machine unit; and a cooling unit. The electrical unit includes a protrusion protruding outward from a left end portion of the rotary electric machine housing portion of the rotary electric machine in a left-right direction. The cooling unit includes: a cooling fan configured to generate cooling air by rotating integrally with a rotary shaft of the rotary electric machine; and an air guide unit configured to guide the cooling air. The air guide unit includes cooling air flow paths provided between the cooling fan and the electrical unit. The closer to the protrusion of the electrical unit a cooling air flow path is disposed, the larger opening area of the introduction port the cooling air flow path has.

Electric power unit

A driving apparatusincludes a motorthat generates drive power and power transmission units, andthat transmit drive power of the motorto an output shaft. The power transmission units, andinclude a brake mechanismthat brakes rotation of the output shaftand a deceleration mechanismthat converts a torque of the motor, and transmits a resultant to the output shaft, and the brake mechanismis arranged at a part before the deceleration mechanism, and the deceleration mechanismis arranged at a part before the output shaft

Driving apparatus

The present invention provides a motor apparatus having a motor, comprising: a fan that is rotatably supported by a shaft member of the motor, and sends, in a centrifugal direction by rotation, gas taken from an axial direction of the shaft member; and a cover member that covers the fan so as to allow the gas sent in the centrifugal direction from the fan to flow along an outer surface of the motor, wherein the cover member has a blowout port that blows out some of the gas sent in the centrifugal direction from the fan in the centrifugal direction to cool an external mechanism of the motor apparatus.

Motor apparatus, electric power unit, and working machine

An electric vehicle that comprises a vehicle main body, a driving apparatus that includes a motor unit which includes a motor and a reduction gear which is attached to the motor unit, and a travel unit configured to drive by a driving force of the driving apparatus. The travel unit includes a plurality of wheels that at least includes a front wheel arranged on the side of a front end portion of the vehicle main body and a rear wheel arranged on the side of a rear end portion of the vehicle main body, and a crawler belt wound around the front wheel and the rear wheel.

Electric vehicle

The electrical power unit is provided with: a power unit body; an electrical component for driving the power unit body; and a connecting terminal which is disposed at the tip end of an electrically conductive path member extending from the power unit body and connectable to the electrical component. The connecting terminal is provided detachably to an attaching portion of the power unit body.

Electrical power unit and work machine

A speed reduction mechanism comprises an output shaft and a plurality of gears. The output shaft is arranged on the same axis as an input shaft. The plurality of gears transmit a driving force input to the input shaft to the output shaft. The plurality of gears include an input gear provided on the input shaft, an output gear provided on the output shaft, and a plurality of transmission gears arranged side by side in a circumferential direction of the input shaft.

Speed reduction mechanism

A driving apparatus 100 includes a motor 20 that generates drive power and power transmission units 30, 40, and 50 that transmit drive power of the motor 20 to an output shaft 60. The power transmission units 30, 40, and 50 include a clutch mechanism 30 that switches between a state where the motor 20 and the output shaft 60 are connected and a state where the motor 20 and the output shaft 60 are disconnected, and a brake mechanism 40 that brakes rotation of the output shaft 60, and the clutch mechanism 30 is arranged so as to overlap the brake mechanism 40 in a radial direction.

A driving apparatusincludes a motorthat generates drive power and power transmission units, andthat transmit drive power of the motorto an output shaft. The power transmission units, andinclude at least one of a clutch mechanismthat switches between a state where the motorand the output shaftare connected and a state where the motorand the output shallare disconnected, in accordance with movement of an operation rod, and a brake mechanismthat brakes rotation of the output shaftin accordance with movement of an operation rod

A driving device includes a motor unit including a motor, and a speed reducer attached to the motor unit. The speed reducer includes a plurality of gears combined to decelerate an output of the motor, and a gear case configured to support the plurality of gears and attached to the motor unit. The gear case is selected from a plurality of types of gear cases. The plurality of types of gear cases are different from one another in an arrangement of the plurality of gears and a position of an output shaft relative to an input shaft.
