Motor esférico: um tipo de posicionador

Abstract

A different conception of spherical motor is presented in this work. The principie of operation is discussed and a mathematical modeling based on the motor’s theoretical conception is developed. In the practical work, several designs are analyzed aiming to reach a definitive prototype. Electronic hardware to drive the motor, an interface to allow the position control via microcomputer, and a position sensor to check also via microcomputer if the motor has reached the demanded position are designed and assembled. Comparisons of theoretical results obtained from mathematical model with experimental tests realized with the final prototype are presented and discussed.
