Abstract

The invention discloses a method and a system for controlling the temperature of a motor. Different treatment can be carried out according to the comparison of the current running temperature of a motor and a plurality of different temperature threshold values, so that the motor works under the precondition of safety. Because the thinning treatment of temperature control is carried out, the temperature of the motor can be better lowered.

Description

technical field [0001] The invention relates to the technical field of motor protection, in particular to a method and system for controlling the temperature of a motor. Background technique [0002] In the 21st century, the global climate is gradually warming, oil prices are rising, and oil resources are exhausted. Energy-saving and low-carbon travel has gradually become the consensus of people. With the continuous emergence of new technologies, new energy vehicles have gradually come into people's sight. [0003] As a key power system component in new energy vehicles, electric motors have a safe and reliable operation that is related to the safety of every car user. How to ensure continuous and reliable operation of electric motors will become the key to the promotion of new energy vehicles. The motor will inevitably generate a large amount of temperature during the working process, and the high temperature will affect the performance of the motor and even cause damage to...
