Abstract

The invention provides a potting tool and method for the inner stator of a motor, which belongs to the technical field of motors. The invention can not only keep the outer diameter of the stator unchanged through the close fit of the sleeve, the tape layer, and the metal sheet and the outer circumference of the stator , and can make the potting glue completely penetrate into the first plastic cavity, the second plastic cavity, and even each narrow gap; injecting the potting glue multiple times and vacuuming can not only discharge the air in the stator to be potted, but also provide The potting glue reserves enough space, and at the same time, it can discharge the air bubbles in the potting glue, so as to ensure the quality of potting and improve the insulation performance of the stator, thereby prolonging the service life of the motor. After the potting is completed, the stator is put into an oven for curing. After the curing is completed, the sleeve and the metal sheet are removed for secondary use. Just tear off the tape layer to obtain a complete stator. Due to the protection of the sleeve, the tape layer and the metal sheet, the potting compound will not overflow to the outside of the stator, and there is no need to clean it.

Description

technical field [0001] The invention belongs to the technical field of motors, and more specifically relates to a potting and sealing tool and method for an inner stator of a motor. Background technique [0002] In most motor stator potting processes, the motor stators involved are all outer stators. The potting tooling of the outer stator is generally to install an elastic airbag in the stator, assemble the stator with the casing, inject the potting glue into the upper end of the stator, and then flow into the lower end of the stator through the gap between the stator and the casing. During potting, the potting glue will stick to the inner diameter of the stator, resulting in changes in the inner diameter of the stator, and the cured potting glue is not easy to clean, affecting the assembly of the stator, rotor and other motor components, and further affecting the production efficiency of the motor. At present, more and more motors adopt the structure of inner stator and o...
