摘要： A method and apparatus for driving an electric vehicle having a synchronous traction motor. A peak value of induced electromotive force of the synchronous motor at a maximum allowable rotating speed is set to a value which is lower than an allowable voltage of the smoothing capacitor of the inverter and lower than a maximum allowable voltage of the power switching elements composing the inverter. The synchronous motor is thus constructed so that a peak value V0max of the maximum induced electromotive force at the maximum allowable rotating speed N2 of the synchronous motor satisfies a relation of V0max≦VCmax where VCmax is an allowable voltage of the smoothing capacitor.

摘要： A device for detecting a load torque using angle detectors fitted with a certain spacing on a shaft which is rotated by a drive source and on the basis of a relative angular difference of angles detected by the angle detectors. The device includes two rotary drums or discs fitted with a certain spacing on the drive side and load side of the shaft, with a plurality of magnetic poles for generating magnetic signals being formed on the surface thereof, and a magnetic sensor disposed to confront the surface of the rotary drums or discs, with magnetic resistance effect elements which vary in internal resistance in response to the magnetism of the magnetic poles being provided thereon. The amount of torsion created by the load on the load side of the rotary shaft is measured as a phase difference of outputs of the magnetic sensor, and the torque is detected in terms of the angular difference between the magnetic drums or discs. The device is operative to detect a torque in both storage and rotation, and capable of detection within a period of magnetic signal, whereby high-accuracy, high-resolution torque detection is made possible.

摘要： A chopper controller for a D.C. motor controls currents flowing in an armature winding and a field winding of the D.C. motor by controlling an armature chopper and a field chopper in accordance with a command from a command generator such as an accelerator pedal. The armature chopper and the field chopper are controlled by chopper control signals from an armature chopper control circuit and a field chopper control circuit, respectively.

In response to the interruption request signal, computing means computes an armature chopper duty factor and a field chopper duty factor in accordance with the command from the command generator and supplies them to the chopper control circuits.
