A constant-speed continuously-running low-powered diesel engine or turbine drives a two-phase alternator the output from, which, for direct drive flows to the stator pole piece windings of four independently-rotating stepping motors operating synchronously with the alternator. Each stepping motor is connected to a traction wheel of a motor vehicle thereby propelling at, limited maximum speed sufficiently to overcome normal wind resistance over a level road. In starting, during acceleration and, for propulsion at lower speeds, direct current from a storage battery is caused to pulsate and is added to the current from the alternator to the stepping motors. A control circuit selectively …
