What are the main faults of the motor stator
The stator consists of a stator core, a stator winding and a base of three parts. The stator's main function is to produce a rotating magnetic field, and the main function of the rotor is in rotating magnetic field by magnetic lines cutting and produce output current.
Stator common failure
The common faults of stator including winding open circuit, short circuit, earthing, tension spring and brush holding poor contact, spring is burnt, a stator fixed bolt loosening and other.
Repair small common sense
In order to achieve the general nature of the stator, some repair personnel on the same core model, the thickness of the change (part of the electric knife used), the number of windings is also integrated average, processing, so that the general purpose of the stator. The small make up suggestion, in order to guarantee the power output, should make the iron core specialization is good. Only by ensuring that the thickness of the original machine can guarantee the performance parameters of the whole machine.
There are 2 sets of stator windings, the 1 groups are field windings, the other 1 is the brake winding, the role is when the excitation winding power, immediately to produce a reverse torque, so that the blade immediately stopped, improve the safety factor.
Industry focus
In 2014, Qiqihar Heavy CNC thoroughly implement the national implementation of the strategy of revitalizing the spirit of the old industrial base of the northeast, to meet the needs of the market, the implementation of the overall technical upgrading project ". By eliminating backward production capacity, adjust the process layout, new high precision machining equipment, through the modern information technology and high-tech means, the establishment of high-end product research and development and manufacturing, scientific research and experimental research, precision machining and high-end CNC equipment assembly and debugging industrial base.
New 45000 square meters in the south of the modern machine plus the integration of the workshop, clean environment, uniform machine tool products, specifications, the export of high-end machine tools, intelligent equipment to let visitors refreshing. Miao Wei came to the car in high precision vertical milling machining center, a careful understanding of the machine tool innovation. This machine tool is the enterprise and Harbin Institute of technology, Huagong Electric Technology Co., Ltd., the joint development of, and table spindle for the first time by torque motor direct drive to achieve the main rotating torque turning and high precision of C axis rotary feed, efficient, high reliability, high life, green manufacturing, belonging to the a first domestic and international leading is a revolution in the history of the development of machine tool main drive.
Through on-the-spot investigation, Miao Wei spoke highly of Qiqihar heavy cnc. He said these years, Qiqihar Heavy CNC done very well, enterprise restructuring reform is very successful. At present, enterprises need to further strengthen information management, improve the degree of automation, in order to provide users with products, but also provide the port, thereby further improve the profit space. At the same time, we hope that the development of the enterprise can drive the numerical control system to support the domestic equipment more and more, and make a greater contribution to the development of our national industry.
