Control de velocidad por cambio de frecuencia de motor trifásico sincrónico usando microcontroladores avanzados e interfaz serial para la visualización de resultados

摘要

The project presented below, describes the operation, development and implementation of a prototype enginecontroller for brushless motors BLDC (Brushless Direct Current) with and without Hall Effect sensors, developedby Microchip in application notes AN857A and AN957. These notes develope two types of programs one in ASM(assembler) language, that handle a BLDC motor without Hall effect sensor and the another for BLDC motors withHall effect sensor. This project implemented both programs.Furthermore, this report describes the application using the PIC16F877A microcontroller, which will serve tocontrol the project. In this device will be programmed both of the selected for this implementation. The project willdescribe the operation, structure and operation of the BLDC motor and the Hall effect sensor. Complemented withthe implementation of the power phase of the speed controller, comprising a three-phase H bridge designed with NtypeMOSFET's
