WEG, the international leader in drive technology and its subsidiary Watt Drive has launched the new modular EUSAS motor. The motor will be available as an integral motor for gearboxes and as standard induction motor with mounting positions B3, B4 and B14. The motors are initially available in two-pole, four-pole and six-pole versions with IEC 63 to IEC 160 frame sizes and power ratings from 0,12 to 18.5 kW. Frame sizes from 180 to 315 will be available in future. The EUSAS motor is the first to combine the energy-efficient WEG motor technology with Watt Drive’s MAS modular gear unit system. Because of their wide voltage range and simple voltage reconfiguration in the terminal box, these system motors can be used globally at a wide variety of mains voltages (100V to 690V) and frequencies (50 Hz and 60 Hz).
The EUSAS motor has a specially designed wide-range winding, with each motor’s winding divided into two partial windings with a total of twelve leads – providing a large range of wiring options on the nine-bolt terminal board. This allows the motor to be wired for up to four different voltage level (Y, delta, double Y or double delta) configurations, which makes it highly versatile. Until now, induction motors have been severely limited in terms of voltage configuration options due to their winding design. A separate motor version has been necessary for each voltage level deviating from the IEC60038 standard, resulting in considerable additional cost and longer delivery times, especially for smaller quantities. The special winding design of the EUSAS motor ends this limitation and WEG claims the motor is a versatile all-in-one solution.
