Motor with variable magnet flux

According to the present invention, a motor having a variable magnetic flux includes a rotor and a stator located inside the rotor. The rotor includes a rotor housing, a rotor core attached to an inner circumferential side of the rotor housing, and magnets attached to the inner surface of the rotor core. The stator includes a stator core base and a plurality of teeth radially formed on an outer peripheral surface of the stator core base with an equal interval. Each of the teeth has ears formed at both sides of an end thereof. The magnets comprise first magnets and second magnets. The coercive force of the second magnets is lower than a coercive force of the first magnets. A plurality of the first magnets is located at both sides of the second magnets.
