Rewinding motor coil, self-made winding die, how to choose the thickness of die core?
The following are some suggestions about the thickness of the mold core:

According to the design requirements: first of all, you need to know the design requirements of the motor coil you want to rewind. Design requirements usually give some guidance on the thickness of the die core, which is determined after comprehensive consideration of the power, current and use of the motor. Therefore, consulting relevant motor design documents or consulting professionals can get more accurate values of die core thickness.

Heat transfer and heat dissipation performance: the thickness of the mold core is also related to the heat transfer and heat dissipation performance of the motor. If the thickness of the mold core is too thick, it may affect the heat transfer between the coil and the mold core, leading to an increase in temperature and affecting the working efficiency and life of the motor. At the same time, if the mold core is too thin, it may not provide enough structural support and insulation protection. Considering the requirements of heat conduction and heat dissipation, an appropriate mold core thickness can be selected.

Line diameter and number of layers: the thickness of the mold core is also affected by line diameter and number of layers. Larger diameter coils usually require thicker cores to provide adequate support. More layers of coils may also require thicker cores to better fix and isolate wires of different layers.

Insulation performance: the thickness of the mold core should also consider insulation performance. The insulation layer in the motor coil is very important, which can protect the wire and coil from short circuit and leakage. The thickness of the mold core should be enough to provide good insulation protection to ensure the safety and reliability of the motor.
