  "textContent": "This application discloses a motor, a motor controller, a heat exchange system, and a control method, and relates to the motor field and is used to improve motor heating efficiency. The motor includes a housing, a stator mounted inside the housing, a rotor connected to the housing through a bearing, a winding wound on the stator, and a liquid inlet hole and a liquid outlet hole that are connected to a cavity in the housing. The liquid inlet hole is used for inflow of an insulation coolant, and the liquid outlet hole is used for outflow of an insulation coolant. The rotor includes a rotating shaft, a rotor iron core mounted around the rotating shaft, and a permanent magnet mounted on the rotor iron core. A first hole channel connected to the cavity is disposed on the rotor iron core. The winding is configured to input a direct-axis alternating current.",
