Abstract: A method and system for the sensorless estimation of the states of the mechanical subsystem of a motor are disclosed. In particular, the method and system split the estimation problem into two sub-problems: the estimation of motor parameters as a function of position, and the determination of the states of the mechanical subsystem of the motor using the estimated parameters via a state observer. Motor current and PWM voltage in a polyphase system is measured or otherwise determined and converted into current and voltage in ?-? coordinates. A least square estimator is constructed that uses the voltage and current in ?-? coordinates and provides an estimate of the motor parameters, and in particular, the inductances of the motor, which are a function of the rotor position.
