Resumen
Speed and position estimator of a synchronous motor of permanent magnets based on the procurement of the motor counter electromotive force.The present invention refers to a speed and position (8) estimator of a synchronous motor of permanent magnets (6) based on the procurement of the motor counter electromotive force. The use of the estimator prevents the use of sensors of these quantities, enhancing the reliability in the applications of the motor such as the adjusted electric operation. The estimation of the position and speed is performed by obtaining, through the voltages and currents, the motor counter electromotive force, quantity that links the electric quantities of the motor (voltages and currents) with the mechanical quantities (speed and position).<IMAGE>
