Claim Text:
1. A motor control system, comprising: a transform component configured to receive current values associated with a motor being driven by the motor control system, and output rotating coordinate system values representing a flux generating component and a torque generating component of a current space vector, wherein the transform component comprises: a control component configured to receive the flux generating component and the torque generating component of the current space vector, and generate motor control signals for driving the motor by performing a Cartesian to polar transform to obtain values associated with a rotating coordinate system followed by an addition with a position angle to convert the rotating coordinate system values to values of a stationary coordinate system to generate a voltage space vector, wherein the control component further comprises: a position estimator component configured to generate the position angle employing the Cartesian current values from the Clarke transform component and Cartesian voltage values based on the voltage space vector output from the control component.
