Abstract

The invention discloses a method for acquiring transient temperature field of a motor. The method comprises the following steps: S1, acquiring a first finite element model of the motor; S2, performing reduced order processing on the first finite element model to obtain a reduced order model of the motor; S3, solving the reduced order model to obtain a computed result of the reduced order model; S4, mapping the computed result to the first finite element model to obtain the temperature mapping, at different moment, of each node in the first finite element model. Compared with the prior art, the method for acquiring the transient temperature field of the motor, disclosed by the invention, not only is capable of ensuring the accuracy of an acquired result of the transient temperature field but also reducing the amount of computation and increasing the computation efficiency; meanwhile, compared with methods in the prior art, the method for acquiring the transient temperature field of the motor, disclosed by the invention, not only is high in adaptability but also is simple in operation, and higher in operability and practicability.

Description

technical field [0001] The invention relates to the technical field of analysis and measurement control, in particular to a method and device for obtaining the transient temperature field of a motor. Background technique [0002] As an electromechanical energy conversion device, the motor will produce losses such as iron loss, copper loss and mechanical loss during operation, which will cause the temperature of the motor to rise. The temperature rise of the motor is directly related to the service life of the motor, and it also has a certain impact on the output and efficiency of the motor. The specific parameter of motor temperature rise is one of the important indicators to measure the performance of the motor. Therefore, in the process of measuring the performance of the motor and monitoring the working state of the motor, thermal analysis, especially transient thermal analysis, is usually performed on the motor to obtain the temperature field of the motor. [0003] At ...
