Motor and hairpin-shaped wire stator thereof

A hairpin wire motor stator includes an iron core, a plurality of slots, a first hairpin wire, and a temperature sensor. The annular iron core defines a rotor accommodating space. The plurality of slots are located on the iron core, and each slot is far away from the rotor accommodating space along the radial direction of the iron core and is used for accommodating multiple layers of hairpin-shaped wires. Each slot is provided with a side opening adjacent to the rotor accommodating space. And at least one of the slots is a temperature sensor accommodating slot. The first hairpin-shaped wire is located in the temperature sensor accommodating groove and is close to the side opening of the temperature sensor accommodating groove. The temperature sensor is located between the side opening of the temperature sensor containing groove and the first hairpin-shaped wire, and the temperature sensor is larger than the side opening of the temperature sensor containing groove, so that the temperature sensor is wrapped in
