Abstract
Un controlador de motor (4) y método para maximizar los ahorros de energía en un motor de inducción AC (3) en cada carga en donde se calibra el motor en dos o más puntos de carga para establecer una línea de control (6), lo cual después se programa en una memoria no volátil (30) del controlador de motor. Un controlador de motor de bucle cerrado basado en DSP observa los parámetros de motor del motor tal como ángulo de encendido/ciclos de trabajo (23), voltaje (37), corriente (9) y ángulos de fase para legar a un voltaje mínimo necesario para operar el motor a cualquier carga a lo largo de la línea de control. El controlador de motor realiza control de bucle cerrado para mantener el motor corriendo en un punto de control objetivo calculado, para que se realicen ahorros de energía máximos al reducir el voltaje a través de la modulación de anchura de pulso.A motor controller (4) and method to maximize energy savings in an AC induction motor (3) at each load where the motor is calibrated at two or more load points to establish a control line (6), which is then programmed in a non-volatile memory (30) of the motor controller. A DSP-based closed loop motor controller observes motor motor parameters such as ignition angle / duty cycles (23), voltage (37), current (9) and phase angles to reach a minimum required voltage to operate the engine at any load along the control line. The motor controller performs closed loop control to keep the motor running at a calculated target control point, so that maximum energy savings are realized by reducing the voltage through pulse width modulation.
