| 目的 研究电机在不同工况下的温升情况，完成电机散热能力评估，为电机散热优化和工程通风设计提供参考。方法 模拟驱动机构实际运行环境，在断风条件下进行自然散热温升试验，获取电机温升最大工作模式，并在该模式下进行2种风速条件下的通风试验，获取定子绕组的平衡温度。当定子绕组达到热平衡后，切断通风，进行断风试验，获取最大断风时间。结果 电机温升最大时，工作模式为三相通电，增大风速可降低定子外壁温度，提高定子绕组与定子外壁的温差。三相通电工况下，5 m/s和8 m/s风速下最大断风时间分别为15 min和22 min。结论 开展了电机温升试验研究，获得了典型工况下电机的温升状况，为电机散热优化和工程通风设计提供了参考。 |

| The purpose of this paper is to study the temperature rise of the motor under different working conditions, complete the evaluation of the motor's heat dissipation capacity, and provide a reference for the optimization of motor heat dissipation and engineering ventilation design. This paper simulates the actual operating environment of the driving mechanism, conducts a natural heat dissipation temperature rise test under the cut-off condition, obtains the maximum temperature rise of the motor working mode. In this mode, the ventilation test is carried out at two wind speeds to obtain the equilibrium temperature of the stator winding. When the stator winding reaches thermal equilibrium, cut off the ventilation and perform a cut-off test to obtain the maximum cut-off time. The results show that when the temperature rise of the motor is at its maximum, the working mode is three-phase energization. Increasing the wind speed can reduce the temperature of the outer wall of the stator and increase the temperature difference between the stator winding and the outer wall of the stator. Under the three-phase energization condition, the maximum wind cut-off time at wind speeds of 5 m/s and 8 m/s is 15 min and 22 min, respectively. By carrying out the motor temperature rise test research, the temperature rise of the motor under typical working conditions is obtained, which provides a reference for the optimization of motor heat dissipation and engineering ventilation design. |
