Present-day motor drives are using voltage inverters for motor speed controlling. Voltage inverters control systems are based on microprocessor technology. Microprocessors, that are used in inverters control systems can also be used for motor drives state estimation. Propositions of algorithms, that are possible to implement in motor drives control systems are presented in the paper. It's suggested to use moving RMS and average values of chosen signals available in control algorithms. Moving values calculation algorithm is presented in C++ language code, so it is possible to implement it in an own solutions. Propositions of algorithms are supported by simulations and laboratory tests results of a motor drive with Field Orientation Control method.
