# 屏蔽电机温度场分析Analysis of Temperature Field of the Canned Motor

Abstract:
The canned motor which has complex structure and large loss is mainly used in the transportation of liquid chemical, and its safe operation and stability is very important. Taken a canned motor as an example, physical model of three dimensional fluid and temperature coupled field was established according to hydromechanics and heat transfer theory. The temperature distribution of motor under nominal working condition was calculated by using finite volume method. By calculation, revealing the regularity of temperature distribution of canned motor and obtaining the conclu- sion that the temperature rise of stator strands and stator core are high, the temperature rise of rotor bars and rotor core are low, the location of maximum temperature rise of motor is in the upper end of stator stands, which provided the the- ory basis for structure design and accurate calculation of larger capacity canned motor.
