Electrical powerplant for vehicles

An electrical power plant for a vehicle, particularly an automobile, comprising

• a battery (1);
• at least one 12- or 24-pole three-phase disk-rotor motor (6) with a shaft operatively coupled to a wheel, said motor comprising
• a disk-rotor with conducting strips mounted on the motor shaft, and
• circularly arrayed magnets of alternating polarities on either side of the rotor equipped with iron returns outside the rotor periphery;
• and
• means for controlling said motor including a power supply having variable amplitude and frequency, said power supply comprising
• a three-phase DC-AC inverter (16) connected to receive DC voltage from said battery and to generate a high-amplitude three phase voltage;
• an AC-DC rectifier (17) and a smoothing circuit (18) connected to the output of said inverter to receive and rectify said three-phase voltage into DC voltage;
• a pulse-width control (19) connected to receive the output of said smoothing circuit and having an output variable in pulse width and pulse repetition rate;
• and
• circuit means connecting said output of said pulse width control to a three-phase winding of said disk-rotor motor.
