Mirror shaft processing manufacturers tell you how to measure the shaft voltage of the generator? The following is a detailed introduction by Long Feng Machinery for everyone, I hope to help everyone!


Axis voltage measurement


U1 grounding voltage: excitation terminal bearing bracket


U2 axis voltage


Grounding voltage of U3: steam terminal shaft


Measure U2 before measuring and measure the grounding voltage of the U1 excitation terminal bearing bracket. When measuring U1, a copper brush should be used to short the bearing housing and the shaft, otherwise the oil film resistance between the bearing and the shaft will affect the measurement results. Usually U1=U2, if the difference between U1 and U2 is greater than 10%, it means that the insulation pad is not well insulated. When the insulation mat is not good, U1 and L2; U2, use three 10V AC voltmeters in the measurement. If there is no such instrument, the voltage can be increased by appropriate boosting and then the voltage can be measured with a common voltmeter. The measurement wiring must be connected to a dedicated brush and brushed with a 300 mm handle. When measuring the shaft voltage, the same reliable ground point should be used as the reference point. When measuring, the generator should maintain the rated voltage and measure at rated load, 0.5 rated load and no load.


Dongguan Longfeng Machinery Co., Ltd. specializes in the production of high-precision mirror shaft rods and mirror shafts for automobiles, locomotives, computers and home appliances. The roundness is less than 0.15um, the surface roughness is less than RA0.02um, the straightness is 300mm within 2um, the coaxial is less than 2um, and the size is within 1.5um.


The company is specialized in the production of grinding machines, lathes, milling machines, boring machines, punching machines, heat treatment equipment, surface treatment equipment, etc. in Taiwan, and is a technology combination company of Taiwan, Japan, Europe, America, Thailand, Malaysia. India has successfully transferred more than 60 manufacturers to produce high-quality production examples, and because the domestic supporting market is a relatively closed stage, most of the high-quality shafts are required to rely on imports.


The above is the related information introduced by Xiaofeng Machinery of the mirror axis processing factory. If you need to know more, please contact us!
