<p>This electric motor (1) includes: a first rotor (10) and a second rotor (20) that rotate around a rotation axis (Zr); a stator (30) that is provided between the first rotor (10) and the second rotor (20), surrounds the rotation axis (Zr), and has 3 × n slots; and multiple windings (33) that are provided in the respective slots. The numbers of magnetic poles of the first rotor (10) and the second rotor (20) are two even numbers selected from a group of even numbers that are obtained by changing k in a mathematical expression 2 × m + 6 ×n × (k - 1) with m and n being fixed, with the exclusion of a group that includes the smallest even number that is a multiple of 3 × n/2 and multiples thereof. In this case, m, n, and k are integers equal to or greater than one, and the maximum value of m is 3 × n - 1.</p> |
