The invention relates to a passive cooling system for a new energy automobile motor. The systemnew energy automobile motor passive cooling system which comprises a temperature sensor, a refrigerationend, a heat dissipation end, a controller, a drive control module, a support stepping motor, an electromagnetic power-on switch module and a cooling devices. The cooling device comprises a support, anelectromagnet, a magnetic body, a heat storage medium, a heat transfer unit, a heat transfer control unit, a heat absorption end and a heat release end. The magnetic body and the electromagnet generate magnetocaloric effect to form a the heat absorption end and a the heat release end; a plurality of cooling devices are connected in series, so that a large temperature difference is formed betweenthe two ends; the refrigeration end with low temperature cools the motor system; the high-temperature heat dissipation end dissipates heat through airflow at the bottom of the vehicle; meanwhile, a temperature sensor is installed on the motor system to measure the temperature in real time and feed back the temperature to a controller, the controller controls whether the cooling device and the support operate or not, the motor system is always at the most suitable operating temperature, and under the condition that the cooling efficiency of the cooling system is improved, the equipment size isreduced under the condition that the cooling efficiency of the cooling system is improved, natural airflow is reasonably utilized, and energy consumption is reduced.
