  • MOTOR
    Publication number: 20260155713
    Abstract: A motor includes a stator including (i) a stator core, (ii) an insulator disposed at the stator core, and (iii) a coil wound around the insulator, a rotor configured to rotate relative to the stator, and a temperature sensor that is in contact with the coil and configured to measure a temperature of the coil. The temperature sensor has a first region and a second region that are spaced apart from each other in a circumferential direction of the temperature sensor and that are surrounded by at least one of the coil or an insulating member.
