Abstract:
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 disk 45 and a second disk 50, a first ring core 10 having a first switching winding 15 divided into a winding part and a gap part, a second ring core 12 having a second switching winding 20 divided into a winding part and a gap part, and a first rotor 35 having a third disk 25 and a second rotor 40 having a fourth disk 30 mutually connected by a driving shaft 60. The first and second switching windings 15, 20 include first and second power supplies 125-1, -2, and first and second switches 75-1, -2, respectively.
