Description

Technical Field

[0001] The utility model relates to the technical field of motor stators, in particular to a motor stator with an installation error-proofing structure. Background Art

[0002] During the installation of the motor stator, an upper frame and a lower frame need to be installed at both ends of the stator core. In the existing technology, manual installation is usually adopted. Because the upper frame is provided with a limit structure of the lead wire, the installation direction of the upper frame needs to be fixed. The installation worker is prone to wrong installation during the installation process, and needs to rework later, which reduces the efficiency of the installation. In addition, there is no fixing structure for the copper wire and the lead wire crimping end on the upper frame, which makes it easy to cause the copper wire and the lead wire crimping end and the lead wire to shake during the use of the motor, which is easy to interfere with the use of the motor. For this reason, a motor stator with an installation error-proofing structure is proposed. Summary of the invention
