Abstract

The aim of this invention is to develop a low-cost digital driving and control system for brushless DC motor. In this scheme, an estimation algorithm implemented in a microprocessor is utilized via only one hall-sensor feedback signal to detect the rotor position of a multi-poles DC brushless motor for the high-torque low-speed driving and control object. Moreover, the field-weakening method is also adopted for the high-speed control in this invention. Compare to the conventional driving and control system of brushless DC motor with three hall sensors, the proposed methodology has the merits of low manufacturing expenses and simple hardware setup. It can easily implement the proposed framework into the direct-drive transmission mechanism with the requirement of high-torque and high-speed characteristics.
