SYNCHRONOUS MACHINE ROTOR MONITOR WITH COIL INDUCER USING SIGNAL WITHOUT CARRIER INJECTION SENSOR AND EXCITATION CURRENT

摘要

An example of a method (100) for launching an operation of a coiled inductive synchronous machine (10) in a motor mode comprises estimating (110) an initial position of a rotor (38) of a synchronous inductor machine wound (10) using a stimulation signal without an injection sensor (66). The method (100) follows (120) an operating position of the rotor (38) based on the current harmonics of the coiled inductive synchronous machine (10). The method also calibrates (130) tracking (120) using the estimated initial position.
