Motor rotor life prediction method and torque impact mechanism applied to same

The invention provides a method for predicting the service life of a motor rotor and a torque impact mechanism applied to the method, and relates to the technical field of motor rotors, and the method comprises the steps: obtaining a maximum torque interval, formulating a plurality of torque test strategies in the maximum torque interval, and calculating the service life of the motor rotor according to different torque test strategies; the impact torque is periodically applied to the rotor test piece, whether the rotor test piece is damaged or not is judged, the single service life corresponding to different torque test strategies is obtained, then the torque strategy database is obtained, valuable reference is provided for follow-up product research and development, production and maintenance, research and development cost and time are effectively reduced, and production efficiency is improved. 本发明提出一种电机转子寿命预测方法及应用于该方法的扭矩冲击机构，涉及电机转子技术领域，其中转子寿命预测方法，通过获取最大扭矩区间并在其中制定多个扭矩测试策略，按照不同扭矩测试策略，周期性地对转子测试件施加冲击扭矩，判断转子测试件是
