W21 aluminium motors
W21 aluminium motors
WEG aluminium frame motors with removable feet were specially designed to meet market requirements in reference to mounting flexibility since they allow all mounting positions. The foot mounting system offers great flexibility and allows changing of the mounting configuration without requiring any additional machining process or modification to the motor feet. Motor terminal boxes can be rotated at 90 degrees allowing motor leads to be connected at any motor side. Besides that these motors are fully interchangeable with existing cast iron frame motors. Reduced stock is needed as only one motor is required for all mounting positions.
Technical characteristics:
- output: 0,12 kW to 37 kW;
- number of poles: 2, 4, 6 and 8;
- frequency: 50 Hz;
- voltage: 220–240/380–415 V (up to 100 L);
- 380–415/660 V (from 112M and up);
- frames: 63 to 200 M/L;
- color: RAL 5009 – blue.
Features:
- multimounting – flexible and easy to change mounting configurations without requiring machining operations or additional changes to the motor feet;
- aluminium frame provides high protection to the enclosures offering better heat dissipation;
- definite purpose derived lines – W21 aluminum multimounting motors line counts on, besides the General Purpose line, several definite purpose derived lines, such as Brake Motors, Single–Phase Motors and Fan & Exhaust Motors (TEAO);
- the introduction of the 160, 180 and 200 frames allow the W21 aluminium multimounting line to cover rated outputs up to 37 kW, enabling this line to cover even more applications;
- WISER insulation system – increases stator electrical strength and allows the motor operation by frequency inverters, without damage by voltage peaks.
Applications: pumps, compressors, air conditioning systems, fans, cranes, conveyors, machine tools, winding machines, drawing machines, presses, hoists, cranes, elevators, looms, grinders, injectors, extruders, cooling towers, packaging machines, etc.
