1. After the winding is embedded and connected, the ends of the winding should be arranged neatly before binding, and the insulation of the ends should be carefully checked. If there is any displacement, slippage and damage, it should be corrected and trimmed.

2. Tap the inner side of the coil end with a rubber hammer under the pad of the tapping bar, and tap it at the intersection of two adjacent winding ends to make the stator winding ends knock into a whole, which is beneficial to heat dissipation and mechanical strength.
