PEMSES Center houses state-of-the-art equipment for both hardware experimentation and real-time simulation.The lab is equipped with the latest tools and instrumentation necessary for development of power electronic circuits and systems for high power applications.


SAKOR dynamometer









The new line of SAKOR motor testing dynamometers offers high-accuracy testing for designers and manufacturers of electric motors of any size, for use in applications ranging from large industrial equipment to consumer appliances, including fans, refrigerators, and washing machines. They have been optimized so that individual machines can test the widest possible range of motor sizes and still maintain necessary accuracy tolerances. SAKOR systems meet the standards’ tight tolerances and exacting requirements regarding data precision and accuracy. Capable of precisely measuring motor efficiency, these dynamometers provide an essential tool to engineers seeking to reduce fossil fuel consumption and enhance energy efficiency to meet strict environmental standards and regulations.
