Brushless direct current motor controlled by servo system

Abstract

The invention discloses a brushless direct current motor controlled by a servo system. The brushless direct current motor structurally comprises a bolt hole, a fixing ring, a cover plate and a shell, the bolt hole and the cover plate are of an integrated structure, and an outer ring of the fixing ring is fixedly connected to an inner ring of the cover plate in an embedded mode; the shell is composed of an inner frame, a rotating shaft, a permanent magnet and a mounting assembly, the rotating shaft and the permanent magnet are of an integrated structure, the mounting assembly is located below the permanent magnet, vibration is generated in the working process of the motor to promote a control rod to slide up and down at a sliding rail, and in the sliding process, a downward pressing pipe is used for pushing downwards to apply pressure to a shrinkage layer in a rust removal device; when the shrinkage layer is pressed downwards, a placement groove is extruded, so that rust removal liquid on the inner side flows into a moving device through extrusion, then is sprayed out of a communicating pipe, flows through a connecting plate and is sprayed to a sponge layer to soak the surface of the sponge layer, and meanwhile, when the shrinkage layer extrudes the placement groove to stretch out and draw back, the surface of a fixing screw is wiped, and the screw is prevented from rusting under a humid condition.

Description

Technical field[0001]The present invention belongs to the field of servo systems, and more particularly, relates to a brushless DC motor controlled by a servo system.Background technique[0002]The servo system is also known as the flow system, which is used to accurately follow or reproduce a process of control system, brushless DC motor consisting of permanent magnet rotor, multi-stage winding stator, position sensor, etc., through the bottom of the housing The installation through hole is provided, and the top end of the stent is fixed to the specified device when used.[0003]Based on the above-described invention, the existing main existence is insufficient, such as: When applied to a relatively moist region and open space, the screw is placed on the bottom end, the connection is fixed by the screw, which is fixed by the moisture The screw connection at the end face is easy to rust, and the vibration in the process will vibrate the surface of the surface during the motor operation,...

AI Technical Summary

Problems solved by technology

[0003] Based on the inventor’s discovery above, the existing ones mainly have the following disadvantages. For example, when it is applied in a relatively humid area and installed in the open air, the bracket is placed horizontally at the bottom, and the connection is fixed by screws, which are affected by moisture. The screw connection of the end face is easy to rust, and the vibration will shake off the surface rust during the working process of the motor, which will cause a small gap on the connection end face, resulting in poor fixing effect and moisture will flow into the shell from the gap under wet conditions internal, causing internal damage
