[0002] During the production and use of the inductive motor, in order to prevent external moisture from affecting the signal transmission between the inductive motor and the magnetic encoding cover, a sealing and waterproof structure needs to be set between the two. Most of the existing sealing and waterproof structures use sealants and welding structures, that is, by filling sealants between the inductive motor and the magnetic encoding cover, and then welding the outside of the connection between the two to achieve the effect of sealing the connection between the inductive motor and the magnetic encoding cover. Although this method can achieve a sealing effect, it is obviously very inconvenient when the inductive motor or the magnetic encoding cover needs to be inspected and maintained. For this reason, we propose a waterproof structure based on the inductive motor. Utility Model Content

[0022] Working principle: When installing the device, install the fixed head 11 into the periphery of the magnetic encoding cover 2, and fill the sealant into the U-shaped filling groove 14, so that the connection between the fixed head 11 and the magnetic encoding cover 2 can be sealed, and the installation between the magnetic encoding line 10 and the magnetic encoding cover 2 is completed;

[0023] After the two are connected, the positions of the second sealing grooves 5 on the upper end surfaces of the two are aligned with each other, the sealing ring 3 can be installed into the second sealing groove 5, and then the magnetic encoding cover 2 and the motor body 1 are connected to each other. At this time, since the ring width spacing between the second sealing groove 5 and the first sealing groove 4 is smaller than the ring width spacing of the sealing ring 3, the sealing ring 3 can be snapped into the first sealing groove 4 and the second sealing groove 5, so as to achieve the effect of sealing the connection between the motor body 1 and the magnetic encoding cover 2. Finally, the motor body 1 and the magnetic encoding cover 2 can be connected to each other by screws 9.
