Abstract

Una herramienta eléctrica portátil incluyendo: - una carcasa para un motor, - una cubierta de extremo sin accionamiento que tiene un soporte en su centro para dicho motor, - un disipador térmico dispuesto integralmente o por separado en dichas cubiertas, - inversor de puente PWM que consta de transistores de potencia con puertas correspondientes, la salida de dicho inversor de puente PWM está conectada a dicho motor, - los terminales de dichos transistores de potencia están conectados a una placa de circuitos impresos (PB) y están montados en dicho disipador térmico, - la unidad controladora que tiene un programa de software de corta longitud de código y el CI excitador para excitar dichas puertas están conectados a otra placa de circuitos impresos (CB), - dichas dos placas (PB y CB) están interconectadas para determinar las secuencias de temporización para generar las señales para activar/desactivar las puertas de los transistores de potencia de dicho inversor de puente PWM para producir formas de onda sinusoidales de voltaje variable y frecuencia variable (VVVF) para controlar la velocidad de dicho motor usando técnicas de modulación de impulsos en anchura de espacio vectorial (SVPWM) o modulación de impulsos en anchura sinusoidal (SPWM), y están montadas mediante medios de montaje en dicho disipador térmico, - unos medios de enfriamiento montados en el eje de dicho motor para enfriar primero la electrónica de PB y CB montadas en el disipador térmico y enfriar después el estator del motor, - un rectificador de entrada y los condensadores de filtro están conectados al inversor de puente PWM, un suministro de potencia auxiliar, que proporciona el suministro de potencia a la unidad controladora y el CI excitador se alojan en el mango de la herramienta.
