摘要:
A motor with a gear reducer includes a housing, a stator secured to the housing and having an inner periphery thereof defining a central space therein, and a rotor formed of a magnet material and rotatably fitted in the central space of the stator. The rotor has an axial through hole formed therein in coaxial relation to an axis of rotation of the rotor. An output shaft is connected through a gear reducer to the rotor to be rotatively driven thereby, for outputting a rotating output from the rotor through the gear reducer. The output shaft extends through the axial through hole of the rotor and is rotatably supported by opposite ends of the housing. The rotor has a gear forming part of the gear reducer formed thereon at one end thereof, and a hook formed thereon at another end thereof and engageable with a moving device such as an assembly jig in an axial direction of the output shaft.

Electric vehicle of the present invention includes left and right traveling units, and left and right electric motors for driving the left and right traveling units. Speed adjusting lever for adjusting a speed of the left and right traveling units is provided on an operation panel that is in turn provided on a machine body. The speed adjusting lever includes left and right spot-turn switches provided thereon. When the left spot-turn switch is turned on, the left electric motor rotates in a reverse direction while the right electric motor rotates in a forward direction. When the right spot-turn switch is turned on, the right electric motor rotates in the reverse direction while the left electric motor rotates in the forward direction.

An electric vehicle has traveling units, first and second electric motors for driving the respective traveling units, a speed adjusting lever for adjusting a speed of the traveling units, a speed adjustment mechanism for generating a speed adjusting signal in response to operation of the speed adjusting lever, and a control unit for controlling rotation of the first and second electric motors in accordance with the speed adjusting signal generated by the speed adjustment mechanism. The speed adjusting lever has spot-turn switches operable to cause the respective electric motors to rotate in a reverse direction and simultaneously cause the electric motors to rotate in a forward direction, a rotational-angle restriction mechanism that restricts a rotational angle of a rotational operating member, and an automatic return mechanism that automatically returns the rotational operating member to a neutral position upon removal of an operating force having turned the rotational operating member in a first direction or in a second direction from the neutral position.
摘要:
In the working machine wherein the output of an engine generator is directly supplied to a motor for travel without using the intermediary of a battery, preventing the engine from slowing down. The generator G is directly connected to the motor 7 and there is no battery that stores the output of the generator G. CPU 102 decreases the power supply for the motor 7 when it has been anticipated that the engine revolutions will be decreased. The number of the engine revolutions is detected according to the period of the waveform of an output of the generator G. The alternating current waveform that has been drawn out from one phase of the winding of the generator G is shaped into a rectangular waveform. CPU 102 detects the period of the shaped waveform. When the detected period has become larger, the CPU 102 determines that the engine revolutions is about to decrease.

摘要:
An electric vehicle driven by at least one electric motor is provided. The vehicle includes a controller for controlling the electric motor and at least one braking device. The controller gradually reduces the rotational speed of the electric motor in accordance with a vehicle drive stop instruction, and operates the braking device when the rotational speed of the electric motor is equal to or lower than a predetermined rotational speed to stop the travel of the vehicle.
摘要:
A dual-motor electric vehicle having a control section that determines whether three conditions are satisfied, (1) that a straight-ahead travel instruction has been supplied to the vehicle, (2) that an actual number of motor rotations of an electric motor is less than a target number of motor rotations, and (3) that a motor control signal for bringing the actual number of motor rotations closer to the target number has reached a predetermined upper limit output value. When all conditions are satisfied for at least one of the electric motors of the dual-motor vehicle, the control section performs a downward motor-rotation correction process for at least one of motors by incrementally reducing one of the target number of motor rotations and the upper limit output value of the motor control signal until the respective actual numbers of rotations of the left and right motors substantially coincide with each other.
摘要:
Control section determines necessary acceleration of a transporting section in accordance with an actual transporting speed, and also determines a correction coefficient corresponding to the number of rotations of an engine from among correction coefficients having a characteristic of becoming closer to a value of one as the number of rotations of the engine increases. The control section multiplies the necessary acceleration by the correction coefficient to thereby provide corrected necessary acceleration, and controls rotation of a transporting drive motor in accordance with the corrected necessary acceleration. When the amount of electric power to be generated by a power generator driven by the engine has increased, the control section controls the opening of a throttle valve.
