An electric drive that provides power from a DC battery to an AC motor and for charging the DC battery when power is being supplied through the motor windings such that no secondary on-board system for charging the battery or specialized charging station is required. A DC battery is in electronic communication with a three-phase inverter that converts DC power received from the battery into an alternating current when a switch is placed into a closed position. The three-phase inverter is in communication with a three-phase stator such that it supplies the stator with the converted AC power. Once power is received by the stator an air flux and electronic current are produced that interact to produce torque on a rotor creating mechanical energy. When the switch is placed in an open position, the three phase stator discontinues supplying almost all the power to the rotor but rather receives alternating current from an already available three-phase voltage network. The alternating current is transferred into the inverter where it is converted into a direct current that is supplied to the battery to recharge the battery. A control device is provided to control how much power is drawn from and supplied to the battery. |
