[0002] Caseless motors are widely used due to their low cost, good heat dissipation, high power density, and small moment of inertia. However, since the motor has no casing, it is very important to protect the stator core during the manufacturing and transportation process.

[0003] In the current processing of the stoppers at both ends of the stator core, a lifting ring is used to lift and flip the stator core. During the flipping process, the stator core is deformed due to force after contacting the ground and cannot be used. It needs to be repaired manually before it can be used again. The product is unstable, and the repair is time-consuming and laborious. Summary of the invention

The present invention provides a stator core flipping device for a motor without a casing, which is simple in material acquisition, convenient in processing, improves the quality of the stator core, and does not cause deformation of the stator core due to flipping contact force.
