Research on the Main Insulation Overlapping of Stator Coil Ends and Its Mold Design Method
A method based on three-dimensional model to calculate the equivalent number of overlapping layers and the overlapping thickness of the main insulation at the end of the stator coil is introduced.According to the calculation results,the reasons for the weak insulation performance of the stator coil cone angle and the coil corners are analyzed and the calculation method of the ideal mold cavity of the coil mold is proposed,which has positive significance on improving the electrical performance of the stator coil.
