The name of the resistor, the frequency sensitive resistor.

Resistor, frequency sensitive resistor this name have come believe that everyone should be all said frequency sensitive resistor, professionals should be able to operate the product, but if you would like to ask the origin of the name of the product, believe that the broad masses of users to its understanding is not thorough. Today, we have reviewed the relevant information and sorted out the following conclusions, which is the origin of the name of the frequency-sensitive resistor.

First of all, we all know frequency-sensitive rheostat is composed of cast iron or steel sheet pile as core, combined with winding three-phase reactor, in the circuit of the rotor winding, the winding reactance and the decision of the core loss of equivalent impedance changes with the frequency of the rotor current.. The frequency sensitive rheostat actually USES the smooth change of the rotor frequency f2 to achieve the purpose of smoothing the total resistance of the rotor circuit. After startup, the rotor winding is short, and the frequency sensitive rheostat is removed from the circuit. Because the equivalent resistance of the frequency-sensitive rheostat and the electric resistance of Xm are changed with the rotor current frequency, the reaction is sensitive, so it is called the frequency sensitive rheostat.
