1. General information
The WEG W21 series motors are designed to meet specific requirements of some markets. These motors are available in frame sizes IEC 63 to 355M/L. They are suitable for 3 Phase, 50 Hz Supply and are also suitable to operate at tolerances of +- 10% in voltage, +- 5% in frequency and +- 10% combined variation of both voltage and frequency. Additionally, they can operate continuously with a 2% unbalance on power supply voltage.
These motors are supplied with six terminals and are suitable for DOL starting and Star-Delta (except for output ratings below 1.5 kW, which are supplied with internally star-connected winding with three terminals in the terminal box). The minimum Pull Out torque is 210% of the rated torque and the starting current corresponds to 6 times the rated current value. All performance parameters are at rated supply conditions and are subject to tolerance as per IEC standard.
