Manufacturing method of integrated type generator rotor

Abstract

The invention discloses a manufacturing method of an integrated type generator rotor which comprises a rotating shaft. The manufacturing method is characterized by comprising the following steps: punching silicon steel sheets with a punching machine: selecting the silicon steel sheets with appropriate thickness, using the punching machine to punch each silicon steel sheet to form a rotating shaft hole in the center, and four symmetric line slots at the rim of the sheet where four secondary windings can be mounted; forming a core by a pressing machine: overlying and pressing the plurality of silicon steel sheets formed with the rotating shaft holes and the line slots to be the iron core, welding and fixing four symmetric guard posts on the two sides of the iron core; drilling holes and fixedly polishing burs of the iron core; installing the windings and assembling. The rotor winding produced by the method only has two wire joints, which avoids the problem that the connected wire joints are not good in quality; the iron core is integrally formed, so as to avoid magnetic flux leakage, the running temperature rise is reduced, the noise is low, and the voltage is stable. Therefore, the power of the motor and the service life of the motor are increased; the raw material is saved; the manpower is saved by 5 times; the cost is greatly reduced. The manufacturing method conforms to the requirements on national energy conservation and environment protection, and solves the major problem of dynamic balance of a generator.

Description

technical field [0001] The invention relates to a generator, especially a method for manufacturing a generator rotor. Background technique [0002] A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator. Converted to electrical energy by a generator. Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life. Among the many generators, ST / STC series three-phase AC synchronous generators are mainly suitable for AC power supply for lighting and power in small ships, villages, towns, construction sites, mountainous areas, and pastoral areas. They are widely used and are our main research objects. . The rotor is one of the core componen...

Problems solved by technology

[0012] 2. Since the four electrodes are independent of each other, the gap between them is large, and the magnetic flux leakage is also large. During operation, the temperature rises, the noise is large, the voltage is unstable, and the power is reduced and the service life is short;

[0013] 3. Since the four electrodes are installed independently, it is easy to cause asymmetric deviation, or the asymmetry of the weight of the four electrodes makes the rotor run unbalanced, causing the motor to vibrate
