Development and Performance Investigation of the Direct Brushless Torque Motor

Abstract

The paper deals with the brushless torque motor, that was designed for precise positioning device to substitute servo drive for high torque and low speed application. It describes the design, basic parameters as well as the analysis of torque characteristic. The paper also presents the results of realized measurements. Finally, the parameters of the brushless torque motor and servo drive applicated in precise positioning device are compared. A series of measurements like measurement of torque characteristics, loading characteristics and also measurements of drive performances are presented in this paper.
