Abstract

A design method of a brushless DC type AC servomotor drive system is presented. The servomotor drive system is designed to be applied to factory automation. The AC servomotor used is a trapezoidal type designed and made by Daewoo Heavy Industries Ltd. The drive system consists of a velocity controller, current controller and inverter. In the drive system a power transistor is used as the switching device and a 16 bit, one chip microprocessor is applied for the implementation of digital control. The velocity control algorithm is basically PI control with appropriate filtering. The current controller is also based on PI control, which is implemented in analog circuits to reduce the time delay effect. The designed servomotor drive shows good performance up to a velocity of 4500 RPM, which is sufficient for most factory automation applications.
