PURPOSE: An electric motor is provided to efficiently use the space by obtaining a rotational force larger than that of a conventional motor of a same size and to reduce the size of the motor. CONSTITUTION: Magnetic poles(12,13,14,15) are formed on the inner surface of a core(11) which has a circular closed loop at the interval of 90°. A stator(16) includes wound energized coils(18,19,20,21) in a core between the magnetic poles. A rotor(17) is separated from the magnetic poles, and comprises a permanent magnet installed in the interior of the core(11). The energized coils(18,19,20,21) has a same magnetic flux when the current is applied. The energized coils(18,19,20,21) are wound in the core between the magnetic poles.
