Energy-Efficiency Is The Game
WEG Electric Corp. (Atlanta, GA) adds two new energy-efficient motors to its line: the Quattro and W22 Super Premium. The Quattro is a line-start permanent magnet motor that is more efficient than NEMA Premium efficiency induction motors. The motor operates at synchronous speed regardless of the load, and has the same frame size as an induction motor. In addition, no feedback device required for precise speed control, and the whole motor has low bearing temperatures. On the other hand, the W22 Super Premium motor operates with very low noise levels and high torques, and is the most energy-efficient model in W22 line.
