Investigation of Temperature Field of the Canned Motor of Nuclear Primary Pump

Abstract:

The safe operation of canned motor in nuclear primary pump is very important for nuclear power station. Taken a 5500KW large canned motor of nuclear primary pump as an example, physical model of three dimensional fluid and temperature coupled field was established. The motor temperature distribution under nominal working condition was calculated by using finite volume method. By calculation, revealing the temperature distribution regularity of stator strands, rotor bars, stator core and rotor core, which have significant reference value to structure design of canned motor.
