General Purpose Three Phase Motors TEFC (IP55) High Efficiency. Standard Features

Transcription

1 TM WEG W21 Severe Duty motors meet the most demanding severe duty application requirements. These TEFC motors are all cast iron construction, with enclosures rated IP55 to handle wet and dirty environments. They are painted with WEG s own special system, using synthetic enamel alkyd resin paints, which exceed the ASTM TM B117 standard for salt spray test. The W21 line is rated for 1.25 Service Factor up to 100HP and meet Design B (up to 200HP) and Design C (according to electrical table) torque requirements. This line is rated for dual frequency and dual voltage (with reduced service factor) up to 30 HP. And the entire line is certified Inverter Rated for use with a VFD. This rating meets or exceeds MG1 Part 31 Specifications. WEG s motors are designed to meet or exceed all EPAct requirements for energy efficiency as defined by the DOE. The efficiency values are certified according to the DOE s regulations (Certificate of Compliance number CC029A).
