The disclosure relates to a synchronous permanent-magnet electric motor and a vehicle driven by such a motor. The electric motor has a leakage inductance whose value is at least about 10% of the value of its effective inductance. In this way, the total inductance of the motor is maximized so as to optimize the effect of the variation of the phase of the stator current on the variation of the voltage at the terminals of the motor. The invention is notably applicable to an electric vehicle.

[ What is claimed is:] [1.] A synchronous electric motor, having a back electromotive force, comprising a rotor of one or more permanent magnets and a wound stator, said motor having a leakage inductance value of at least approximately 10% of the effective inductance of the motor, such that the total inductance of said motor is maximized, so as to minimize at high speed, a defluxing component of stator currents, said defluxing component opposing said back electromotive force, in order to keep a substantially constant voltage at terminals of the motor.
