In order to serve the markets that require motors according to the GOST R 51689-2000 (GOST 28330-89) standard, WEG offers the WGOST line, using modern and proven technologies, WEG gives new life to this concept. High efficiency coupled with low cost of ownership throughout the motor’s lifetime have been the basis for the WGOST development. A design created to anticipate concepts in performance and energy savings.
