Aplicaciones y utilidades de los motores brushless. Caso práctico: implementación de un brazo robótico controlado mediante el PC.

Abstract

A robotic arm controlled by the PC was implemented with applications and utilities of brushless motors; it means a system of flight simulation was designed. The robotic arm was built over an acrylic base, in which was placed the propeller brushless motor and it was connected to the module M.E.I&T04, which allows communication with the PC, from the PC using the LABVIEW programming software, signals or voltages to the arm are sent; the tests detected the failings, especially in the stabilization flight part, since, to realize the flight and setting in the "coordinates" data, that the user chooses, there is an instability during the time of a minute and a half until to reach stabilization with a flow of constant speed. The risks of stabilization were detected and identified with the indicator and received values, making its qualification or estimation by the triple criteria method: probability, severity, vulnerability, and after the preventive management was carried out through engineering controls in the source program and in the transmission control means where drives were used for sending signals of voltage activation. With the implementation of the robotic arm, the benefits of brushless motors were known and it was checked its operation and management in relation to the points of reference that were assigned to locate in this coordinate. This study recommends the detection of balance points to get the flight stabilization.
