In a rotating electric machine, an axis direction width of a rotor core arranged at an end of a load side of the rotating shaft is set to be γ, an axis direction width of a rotor core arranged at an opposite side end of the load side is set to be ε, a distance from a support part at the load side to the rotor core at the load side is set to be α, and a distance from a support part at the opposite side of the load side to a rotor core at the opposite side of the load side is set to be β. In a case of α>β, γ≥ε is satisfied, and in a case of α<β, γ≤ε is satisfied. Thereby, the vibration of the rotor can be suppressed effectively.
A rotating electric machine having a stator and a rotor, the rotor provided on a rotating shaft, whose both sides are supported rotatably by support parts, and divided into a plurality of rotor cores,
