  "textContent": "This application provides a motor, a motor cooling system, and an electric vehicle. The motor includes a rotor, the rotor includes a rotor iron core, a first end cover, and a second end cover, and the first end cover and the second end cover are respectively connected to two ends of the rotor iron core. The first end cover is provided with a liquid inlet channel, the rotor iron core is provided with a liquid flow channel, and the first end cover or the second end cover is provided with a liquid outlet channel. The liquid inlet channel connects the liquid flow channel and space outside the rotor, the liquid outlet channel connects the liquid flow channel and the space outside the rotor, and an outlet of the liquid outlet channel faces a stator winding. The liquid inlet channel, the liquid flow channel, and the liquid outlet channel form a rotor channel for a coolant to flow through. Technical solutions of this application can reduce processing costs while ensuring heat dissipation reliability of the rotor of the motor.",
