WEG Electric Quattro and W22 Super Premium motors
WEG Electric Corp. will add two new energy-efficient motors to its line: Quattro and W22 Super Premium. Quattro, a line-start permanent magnet motor, is a hybrid model that features a three-phase distributed winding in the stator. Operating at IEC established IE4 efficiency levels, the company says the Quattro is more efficient than NEMA Premium efficiency induction motors. The motor operates at synchronous speed regardless of the load, providing no I2R losses in the aluminum cage. The W22 Super Premium motor offers maximum efficiency and exceeds NEMA Premium levels with 20% fewer losses. The motor is two efficiency bands over premium motors and operates with very low noise levels and high torques. The W22 Super Premium has a 1.25 Service Factor through the 447T fame size. Both energy-efficient models will be available for order by September 2010.
