Alternating-current electric motor being able to be connected into the charging circuit for batteries

The motor has a three phase motor stator connected to an three phase electric network whose number of phases is less than phases (A', B', C') of the motor, where charging current of the network is injected via one of connection points (AO'-CO') dividing a stator phase connected to an electric network phase into two semi-windings. Each semi-winding includes coils wired together to reduce magnetic coupling of the semi-winding at the point so that the semi-winding occupy the apparent non-zero inductance at the point in a charge mode of a charge and power supply combination electric device. An independent claim is also included for a load and power supply combination electric device comprising an inverter and an electric motor.
