Provided is an electric motor which is simple to design and manufacture, and can be operated by a small current. The electric motor is comprised of a stator (55) having a first stationary permanent magnet (45) and a second stationary permanent magnet (50), a first ring-shaped core (10) having a first switching winding (15) divided into a winding part and a gap part, a second ring-shaped core (12) having a second switching winding (20) divided into a winding part and a gap part, and a first rotor (35) having a first rotating permanent magnet (25) and a second rotor (40) having a second rotating permanent magnet (30) mutually connected by a drive shaft (60). The first and second switching windings (15, 20) have first, second power supplies (125-1, -2), and first, second switching units (75-1, -2), respectively. |
