Control Box Highly Efficient Rotor Resistance

We are the noteworthy manufacturer and supplier of Highly Efficient Rotor Resistance from Howrah, West Bengal, India. Rotor Resistance is a method and apparatus for generating stator and rotor resistance estimate, including the steps of providing high frequency injection voltage signals to a three phase motor, rotating three phase feedback current there from, converting the feedback currents to two phase currents that represent the high frequency component of the current vector wherein the d and q axis components are within a two phase voltage coordinate system and driving a regulator via one of the current components to generate a lag angle estimate, the lag angle estimate used to solve any of several different equations to calculate the stator and rotor resistance estimates.
