W22 Medium Voltage - TEFC

The recently launched WEG W22 series of Electric Motors can also be found in a medium voltage variant. WEG’s medium voltage W22 motors range in availability from 125 to 600 HP, with voltages ranging from 2300 to 6600V and come with 2, 4, 6, and 8 pole options in NEMA frames 449T, 586/7T and 588/9T. The W22 motor has a 4140 steel shaft and RTD’s (2 per phase). Similar to their low voltage sibling, the medium voltage W22 is TEFC IP55 with a top mounted terminal box designed to facilitate maximum flexibility. Standard Features
