Three-phase asynchronous motor current sampling resistance

Sampling resistance is also known as current resistance, electric flu resistance measurement, sampling resistance, current induced resistance. General English translated into from resistor, Current sensing resistor. With simple words description is a resistance smaller resistance, series in the www.dongfeng-motor.com circuit used in the current into a voltage signal is measured. Such resistance, it is divided according to the function of the products use resistance. Sampling resistance function is used as the reference, commonly used in a feedback circuit, stabilized voltage supply circuit, for example, to make the output voltage constant state, want to part from the output voltage is the voltage for your reference (the form of generator set spare parts commonly used sampling resistor), if the output is high, the input is automatically reduced voltage, reduce the output; If the output is low, the input is raising voltage automatically, try output to rise. 


Commonly used in power supply products, or electronic, digital, power supply part of the mechanical and electrical products, powerful. In numerous electronic products are often see sampling resistor. Sampling resistance generally use is precise resistance, low resistance, high precision, generally in resistance precision within + / - 1%, higher requirement of use when resistance with 0.01% accuracy. The majority of domestic production is based on manganese bronze material plug-in small diesel generator resistance, however, the majority of users have more need of strips of high precise resistance to achieve the function sampling, this is in order AC synchronous generator to meet the requirements of product miniaturization product production automation. Able to produce at low temperature coefficient, high precision, low on resistance to meet user requirements manufacturers in domestic is very little resistance.
