1. There is something wrong with the motor model: it may be that there is an error or defect in the motor model itself, which leads to the failure of normal operation during simulation. It is necessary to check whether the design of the motor model conforms to the actual physical situation.
2. Wrong setting of simulation conditions: it may be that the conditions set during simulation are incorrect, such as the wrong setting of parameters such as load and power supply of the motor, which leads to the motor not running. It is necessary to check whether the simulation conditions are consistent with the actual situation.
3. Material property setting: The material property setting of the motor will also affect the simulation results. If the setting is incorrect, the motor may not operate normally. It is necessary to check whether the material properties meet the actual physical conditions.
