Compared to induction motors of the same output and speed, the weight and volume of the equivalent W22 Magnet Super Premium motors is reduced by as much as 77% (refer to example below).  The W22 Magnet motors operate with lower temperature rise even at low speeds. Applications Cooling towers, bag filters, paper machines, paper coil winders, conveyors, pumps, looms, direct current (DC) motor replacements, extruders, compressors, fans, etc.   ![](https://blog.est-aegis.com/hs-fs/hubfs/Imported_Blog_Media/WEG-W22-PM-with-AEGIS-300x240.png?width=300&height=240&name=WEG-W22-PM-with-AEGIS-300x240.png) WEG Electric W22 Magnet Drive Motor with AEGIS installed FRAMES 364T and above The W22 Magnet Drive System composes premium and ultra premium efficiency motors with permanent magnets driven by frequency inverters.  Perfect for applications where speed variation, precise control at low speeds, low noise levels and compact design are critical.  This technology provides the motor with significant advantages such as higher efficiency and a greater power density per frame.  They are driven by WEG CFW11 frequency inverters, which offer constant torque across a wide speed range, operating even at low speeds with efficiency levels above induction motors without requiring forced ventilation. W22 Magnet motors are available in Super Premium (IE4) and Ultra Premium (IE5) versions – the highest efficiency available on the market today.  Due to the dedicated software application which incorporates the vector control technology for driving permanent magnet motors, the use of the WEG CFW-11 frequency inverter and W22 Magnet motor is mandatory.   ![](https://blog.est-aegis.com/hs-fs/hubfs/Imported_Blog_Media/Efficiency-comparison-e1519768527425.png?width=700&height=533&name=Efficiency-comparison-e1519768527425.png) Efficiency Comparison Chart: Black line is W22 Magnet; Blue line is Induction Motor [Shaft Grounding Rings](https://blog.est-aegis.com/tag/shaft-grounding-rings), [AEGIS Shaft Grounding Rings](https://blog.est-aegis.com/tag/aegis-shaft-grounding-rings), [WEG](https://blog.est-aegis.com/tag/weg), [Motors with AEGIS Installed](https://blog.est-aegis.com/tag/motors-with-aegis-installed) ### Subscribe To Our Blog ## Read On ### [Shaft Grounding is Key in Sustainable Building](https://blog.est-aegis.com/shaft-grounding-key-sustainable-building?hsLang=en-us) AEGIS Rings have worked for years to improve reliability and sustainable operatuion of HVAC and... ### [If Your Motor Is On a VFD, Squealing May Be Electrical Fluting Damage](https://blog.est-aegis.com/bearings-squealing-might-be-fluting-damage?hsLang=en-us) **Shaft Voltage from VFDs Damages Bearings** - watch the video to see the shaft voltage that causes... ### [WEG Cooling Tower Motors Are Available with AEGIS Installed](https://blog.est-aegis.com/weg-cooling-tower-motors-are-available-with-aegis-installed?hsLang=en-us) Severe duty is standard with [WEG W22 motors](https://www.weg.net/catalog/weg/US/en/Electric-Motors/AC-Motors---NEMA/General-Purpose-ODP-TEFC/TEFC-Cast-Iron/W22/c/MT_3PHASE_LV_TEFC_W22_CI).
