<p>PROBLEM TO BE SOLVED: To control respective rotors independently, in an electric motor having two rotors sharing a stator.SOLUTION: An electric motor 1 includes a first rotor 10 having a plurality of magnets 13 arranged annularly, and being driven as a 6-phase motor, a second rotor 20 having a plurality of magnets 23 arranged annularly, and being driven as a 3-phase motor, a stator 31 arranged between the first rotor 10 and second rotor 20, and having a plurality of slots 35 in the circumferential direction, and a plurality of windings 33 arranged in respective windings 35. When the number of the slots 35 is 6×s, the number of poles of the first rotor 10 is determined by 2×s×(6×n-5) or 2×s×(6×n-1), and the number of poles of the second rotor 20 is determined by 4×s×(3×n-2) or 4×s×(3×n-1). s and n are natural numbers of 1 or more.</p> |
