A power-assisted wheelbarrow applies an assisting function using an electric motor. Handle shafts connecting to the rear end portions of two handles are covered with grips which are allowed to move axially relative to the handle shafts. More than one steel balls are fitted between the handle shafts and the grips. At the sides of the grips or the handles, pushing force detecting sensors are disposed for detecting the axial movements of the grips relative to the handle shafts in accordance with the pushing forces applied to the grips. The operation of the electric motor is controlled on the basis of the detected values of the two pushing force detecting sensors. As a result, the assisting force by the electric motor can be effectively applied to the wheel of a manual-push type single-wheeled carrier so that manual labor can be reduced while minimizing the consumption of a battery.

In an outboard motor adapted for mounting on a boat and equipped with an internal combustion engine, an electric motor, a battery for supplying voltage to the engine and electric motor, and a controller for controlling the operation of the electric motor, the controller is disposed near the battery. In other words, the controller is not installed on the outboard motor side where the engine and the like are present but on the boat side where the battery is installed. As a result, the effect of the vibration and heat of the engine on the controller is minimized so that the controller can utilize simpler structural features for vibration and heat resistance and is also advantageous in terms of cost.

A electric motor is disclosed in which torque ripple is reduced. The electric motor includes a single motor shaft. Rotors are disposed so as to be mutually offset in phase, and the rotors are secured to the motor shaft. Stators are arranged so as to individually correspond to the rotors, and the stators are disposed so as to be matched in phase. The phases of torque ripple generated in each motor unit, which is comprised of a combination of a single rotor and a single stator, are offset.

A wheel motor for a vehicle has an electric motor which is arranged in a central space defined in a wheel, to rotatively drive the wheel. A gear reducer is also arranged in the central space of the wheel. The electric motor includes a housing fixed to the vehicle body, a stator secured to the housing, a rotor rotatably fitted in a central space defined in the stator to generate the rotative driving force during rotation thereof, and an output shaft connected through the gear reducer to the rotor to be rotatively driven thereby, for transmitting the rotating output from the rotor through the gear reducer to the wheel. The output shaft extends through an axial through hole formed in the final stage gear of the gear reducer and an axial through hole formed in the rotor, and is rotatably supported by opposite end portions of the housing. An electric circuit for driving the electric motor is arranged in the central space of the wheel, together with the electric motor.
摘要:
An inventive headlight and a method for controlling a light distribution of the headlight of a motorcycle effectively eliminating the problem of a deteriorated light distribution pattern of a conventional headlight that becomes apparent typically when the motorcycle is tilted to maneuver the motorcycle along a curved road. A headlight 1 comprises a mirror reflector 3 divided into an upper left movable section 32, an upper right movable section 33 provided with respective pivots 32a and 33a. When the motorcycle is tilted, the tilted or lowered one of the movable sections 32 and 33 is driven to turn upward by a corresponding solenoid type driving unit 5 according to a tilt sensor 22 to face the forward of the moving motorcycle and produce a light 5 distribution pattern aligned with the direction along which the motorcycle moves so that any possible deterioration in the light distribution pattern can be effectively corrected.
