Description

Technical Field

[0001] The invention relates to the technical field of motor rotor winding frames, and in particular to a motor rotor winding frame. Background Art

[0002] In the actual production process of the motor, the coil needs to be wound inside the motor rotor; but when the coil is wound inside the motor rotor, the coil needs to be wound on a winding frame first to assist the installation of the coil. However, when the coil is wound on the winding frame, the ends of the coil cannot be stably fixed at the beginning of winding and after winding is completed, which leads to the loosening of the coil.

[0003] In the prior art, there are also technical solutions for fixing the ends of coils; however, most of them can only fix the ends of the coils at one end; and there is still a risk of the coils loosening. In addition, factors that lead to unstable coil winding include: the coils cannot be tensioned during the winding process and after the winding is completed, which easily leads to unstable coil winding and then loosening. A technical solution is provided for fixing the ends of the coils at both ends; and a technical solution is provided for tensioning the coils at any time during the winding process or after the winding is completed. To this end, the present invention provides a motor rotor winding frame. Summary of the invention
