Abstract
A tooth of a stator is divided into two tooth segments, and an inter-segment gap is formed between the segments. The inter-segment gap is open toward a slot which is a space between adjacent teeth. A cooling fluid is sent to the inter-segment gap from an in-rotor-core flow channel of a rotor core, and the sent cooling fluid directly contacts and cools a coil conductor wiring in the slot.
