Problems solved by technology

At this time, the enamel layer (enamel) of the coil prevents the current conduction between the terminal and the coil, so that the bonding force between the coil and the terminal is reduced, thereby causing a problem that the bonding force between the terminal and the coil is reduced.

Abstract

The present invention provides a coil for a motor, a motor, and a coil processing device for a motor. The coil for a motor includes a core and a coating layer surrounding the core, and an end of the coil is formed on the coating layer and exposes the core. The first groove on the outside, and the second groove formed in a concave manner on the surface of the above-mentioned core and juxtaposed with the above-mentioned first groove, thereby removing a part of the coating layer of the coil in the joint portion of the coil and the terminal, providing protection against The beneficial effect that the coating layer hinders the energization of the coil and the terminal leads to a decrease in the welding quality.

Description

technical field [0001] The present invention relates to a coil for a motor, a motor and a coil processing device for a motor. Background technique [0002] The motor is provided with a rotatable rotating shaft, a rotor coupled to the rotating shaft, and a stator fixed inside the housing, and the stators are provided at intervals along the periphery of the rotor. In addition, a coil forming a rotating magnetic field is wound around the stator to cause electrical interaction between the stator and the rotor, thereby guiding the rotation of the rotor. [0003] The start and end of the coil wound around the stator may be connected by fusing to a terminal for interconnecting the coils or a terminal of a connector. [0004] When the terminal and the coil are welded, current flows in the contact area between the terminal and the coil to generate heat. At this time, the enamel layer (enamel) of the coil prevents the current conduction between the terminal and the coil, thereby red...
