关键字：Fill factor permanent-magnet synchronous motor (PMSM) temperature field temperature rise thermal parameters windings
摘要：This paper presents an equivalent winding model of a small and medium permanent-magnet synchronous motor. The model considers fill factor and void ratio. To verify the model, two winding samples are made. One is annular and adopts ordinary enameled wires. The other is circle but adopts self-adhesion wires. Temperature rises of the winding samples supplied with different current densities are tested. The calculated and tested results were compared. The equivalent winding model is also used for the temperature calculation of a 6-pole/9-slot permanent magnet synchronous motor. The influence of fill factor and void ratio on the temperature rise of the motor is investigated, as well as two overload short time states are compared. Comparing with ignoring the effect of the void ratio, the winding temperature estimation error reduces about 5 degrees C. Finally, winding temperature rises of a prototype are tested. The results can provide some references for choosing a reasonable current density and improving the accuracy of motor temperature estimation.
