PROBLEM TO BE SOLVED: To reduce kinds and make stators common, with stator groups which have the same sectional forms and different lamination lengths, by selecting stators and rotors corresponding to the respective set specification values of a set output torque specification value and a set rotor inertia specification value, out of a stator group and a rotor group. SOLUTION: A stator group is stator cores whose sectional forms are identical, and has a plurality of kinds of stator heights different in the number of laminated layers. A rotor group has one kind of diameter corresponding to a stator hole, and is provided with first rotor groups R1, R2, R3, R4 which use permanent magnets of residual magnetic flux density B, and second rotor groups R10, R20, R30, R40 which use permanent magnets of residual magnetic flux density 2B. Each stator height and each rotor height are set as integer times. The stator and the rotor which correspond to the respective set specification values of the set output torque specification value and the set rotor inertia specification value are selected and combined. Stators are made common, and cost can be reduced. |
