In addition, during the manual bending process, the coil paint film is easily damaged due to the difficulty in controlling the shaping force, resulting in leakage or short circuit.

[0004] Therefore, it is necessary to provide a linear motor stator coil shaping tool to solve the above technical problems. Utility Model Content
