Resumen:
The project presented below, describes the operation, development and implementation of a prototype engine
controller for brushless motors BLDC (Brushless Direct Current) with and without Hall Effect sensors, developed
by 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 with
Hall effect sensor. This project implemented both programs.
Furthermore, this report describes the application using the PIC16F877A microcontroller, which will serve to
control the project. In this device will be programmed both of the selected for this implementation. The project will
describe the operation, structure and operation of the BLDC motor and the Hall effect sensor. Complemented with
the implementation of the power phase of the speed controller, comprising a three-phase H bridge designed with Ntype
MOSFET's
