Title:
回転電機および回転電機セット
Document Type and Number:
Japanese Patent JP7264613
Kind Code:
B2
Abstract:
This rotating electrical machine comprises: a stator including a stator iron core, a stator slot disposed in the circumferential direction of the stator iron core, and a stator winding disposed in the stator slot; and a rotor including a rotor iron core, a rotor slot disposed in the circumferential direction of the rotor iron core, and a rotor bar disposed in the rotor slot. The pole number is within a pole number range consisting of a predetermined plurality of pole numbers. An annular mode number M to be generated by an electromagnetic excitation force is calculated on the basis of a kf-order harmonic order kf included in a distribution of magnetomotive force produced by a current generated by the stator winding, a kp-order harmonic order kp included in a distribution of gap magnetic resistance, a pole number P, a stator slot number Ns, and a rotor slot number Nr. The minimum value among the calculated values of M is set as Mmin, and the stator slot number Ns and rotor slot number Nr are selected for the case in which Mmin exceeds a predetermined value so that a number of stators equal to the selected stator slot number Ns and a number of rotors equal to the selected rotor slot number Nr are included.
