Characteristic evaluation for synchronous motors using a universal drive system

This work proposes a new universal drive system using a real-time interface (RTI). In the universal drive system; the RTI connects real-time simulation software tools with experimental equipment directly. After numerical analysis of the simulation software tools, the RTI takes in an analysis result to the experimental equipment immediately, then an experiment are performed with the experimental equipment. The stability of control systems can be online examined by the experiment. This method is greatly helpful to early carry out the detection and the solution technique of actual problems. Moreover, characteristics of surface permanent magnet (SPM) synchronous motors and synchronous reluctance (SynR) motors are measured using the proposed universal drive system. From the experimental result, it is confirmed that the SynR motor loss becomes small rather than the SPM synchronous motor at the time of high rotation and low torque operation.
