Abstract:Abstract— This paper presents a finite element method approach for motor thermal analysis. Specifically, the 2-D temperature field model of a slotless tubular permanent magnet linear motor is established. The heat convection coefficients of the mover are then calculated based on fluid field analysis. This paper focuses on the winding to obtain an accurate winding temperature gradient distribution and to the highest temperature region from
the high overload motor. Therefore, the improved equivalent
layered model of the ring-shaped winding is particularly applied
to the temperature field simulation of the tubular linear motor.
As verification, the temperature rise of the motor is calculated
accordingly, and the results are compared with the actual experiments.
