AC electric motors WEG WEG W22 IE4

Multi-speed three-phase asynchronous AC electric motors of the company WAY The W22 series, corresponding to the IE4 energy efficiency class, requiring step-by-step speed control. Two-speed electric motors of the brand WAY The W22 IE3 series, made in a cast-iron housing, have the ability to change the speed of rotation of the shaft by changing the number of pairs of poles of the electric motor by switching its windings. In turn, electric motors of this type have a special stator winding, a short-circuited rotor, as well as a high-strength structure. In turn, the windings of two-speed electric motors can be switched according to the following schemes: 4/2 poles (1500 /3000 rpm), 6/4 poles (1000 /1500 rpm). There are also 2 types of two-speed electric motors: with a constant torque on the shaft and with a variable torque. Accordingly, for the needs of industry, WEG produces electric motors with synchronous rotation speeds of 1000 and 1500 rpm. As a rule, electric motors of this series are widely used in industrial presses, pumps, fans, shredders, transportation and belt conveyors, lifting equipment, centrifuges, packaging equipment, grinders, weaving and woodworking machines.
