Abstract

The application discloses a motor suitable for electric vehicles, which includes a motor rotor, a motor stator and a motor control box, and is characterized in that it also includes a motor housing, a liquid inlet device, an exhaust device, an energy storage device, and a pressure regulating device , a vapor-liquid conversion device and a condensing device; the stator shell is a cylindrical shell covering the outside of the motor stator, which together with the motor stator forms a cavity between the shells; the inlet The liquid device plays the role of injecting high-pressure liquid condensate into the cavity between the shells in a limited time; the exhaust device plays the role of discharging the vapor condensate from the cavity between the shells in a limited time; The energy storage device provides an expansion space for the vaporization of the condensing agent; the pressure regulating device is used to timely adjust the pressure inside the cavity between the shells; the vapor-liquid conversion device is used to convert the evaporated condensed The agent converts the gaseous condensing agent into a liquid state by means of pressurization; the condensing device is used for cooling the condensing agent.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a motor suitable for electric vehicles. Background technique [0002] When the electric vehicle motor performs energy conversion, a small part of the loss is always converted into heat. It must continuously dissipate the heat to ensure the normal operation of the motor and reduce damage to the surrounding components; otherwise, insufficient heat dissipation of the motor will lead to the failure of the motor. Reduced lifespan or increased resistance of the motor's internal circuit due to temperature leads to increased power consumption. [0003] The cooling method of the electric vehicle motor used in the prior art is usually air-cooled heat dissipation or natural heat dissipation of the motor; the above-mentioned motor cooling method still has certain limitations for the motor that requires high-speed operation, generates a large amount of heat per unit time, and is sui...
