摘要：
The depth from the open end of a rotor slot closest to a magnetic pole of a rotary core to a slot bottom or the bottom of a subslot provided as a coolant ventilation path on a rotor slot bottom is made less than the depth of slots at and after a second slot counted from the magnetic pole side in the direction of internal circumference, and when a shortest distance between the bottoms of the rotor slots opposed to each other through a magnetic pole or a shortest distance between the bottoms of the subslots is assumed to be a magnetic pole width of the slots, a magnetic pole width Wp1 of a slot closest to the magnetic pole side is set to 85% or more of a magnetic pole width Wp2 of a second slot counted from the magnetic pole side in the direction of internal circumference.
