An electric motor disposed in an electric vehicle includes a stator, a first rotor located at an outer side of the stator, and a second rotor located at an inner side of the stator, wherein each of the first rotor and the second rotor includes a plurality of first permanent magnets and a plurality of second permanent magnets, made of different materials from each other, whereby a material cost can be reduced and an output can be enhanced.

Electric motor and electric vehicle having the same

An apparatus for driving a motor of an electric vehicle is provided. The apparatus includes a capacitor supplied with power by a battery; an inverter configured to include a plurality of switching elements, convert direct current (DC) power stored in the capacitor into alternating current (AC) power in accordance with the switching of the switching elements and drive a motor with the AC power; and a capacitor protector provided between the battery and the capacitor and configured to consume initial power supplied by the battery at an early stage of the supply of power by the battery, the capacitor protector including a common resistor that consumes the DC power stored in the capacitor when the capacitor is discharged. Therefore, it is possible to guarantee the reliability of the apparatus.
