In the stator core, a plurality of slots are formed in a circumferential direction of the stator. The winding is formed by a plurality of conductors which are housed in the slots and are electrically connected. The slots are formed such that a predetermined number of the conductors are housed and arrayed in a radial direction of the stator. The temperature sensor is located in at least one of the slots and detects temperature of the conductors. ## Claims ### Claim 1 A stator, comprising: a stator core in which a plurality of slots are formed in a circumferential direction of the stator;
