ABSTRACT:
A power plant and drive system for an automotive vehicle includes a constant speed 120 volt 3 phase AC motor which is coupled to the drive shaft of the vehicle through a magnetic particle clutch. The 120 volt 3 phase AC motor receives energy from a 120 volt AC alternator which is coupled to the motor through a one to three phase converter and connected in tandem to three 12 V DC alternators. The system further includes a battery driven 12 volt DC motor and a 5 cubic inch gas motor. Some of the energy generated by the 12 volt DC alternators is used to recharge the batteries that power the 12 volt DC motor. In normal operation, the alternators are driven solely by the 12 volt DC motor; however, when the voltage in the batteries becomes lower than 6 volts the alternators are driven solely by the gas motor, thus allowing the batteries to recharge to their normal level. Speed control of the vehicle is achieved by varying the coupling strength of the magnetic particle clutch.
