CAST IRON - LV MOTORS

IEC Standard Motor TEFC This line is designed and built according to European IEC34 and IEC79 standards.

Standard Features: 60 Hz (1.15 Service Factor) and 50 Hz (1.0 Service Factor) Class F insulation (Impregnation Resin and Magnet wire are class H) F2 mounted as standard (F1 convertible) Stainless Steel Nameplate - Laser etched with High contrast background Regreasable ball bearings (Frames 160 and up) Casketed conduit box Class I, Div. 2, Groups A, B, C & D – T3, Class II, Div 2, Groups F & G – T3C (Cast Iron Frames only) Suitable for WYE/Delta Start (W and Y voltage code motors).

Flame Proof Motor W21Xd is an explosion-proof motor especially designed to operate in environments with the presence of explosive atmospheres. It has robust construction, a flame retention system with gaps between the parts carefully designed, accurate machining on the terminal box and screws with high mechanical strength. It meets the requirements of explosive atmospheres like Zone 1 and Zone 2, the W21Xd comply with the efficiency level, specified by IEC 60034-30-1, and with the scope of the European Regulation (when driven by frequency inverters).

The new line is perfect for tough processing applications in almost all industries worldwide. It combines sturdy gear units from WEG's subsidiary WATT Drive with energy-efficient W22X motors, which are available in frame sizes ranging from IEC 71 to IEC 800 and energy efficiency levels up to IE4. Modular Watt gear units can easily accommodate motors with IEC B5 mounting, thanks to the ATEX 95 certified adapters for frame sizes ranging from 71 to 225. When it comes to frame sizes from 100 to 225, torque transfer between the motor and the gear unit is handled by form-fitting, zero-backlash claw couplings, with vibration and shock effectively dampened by an elastic coupling spider (98 Shore A). On request, return stops can also be integrated into the IEC adapters so that the explosion-proof drives can be used in applications where reverse operation must be prevented, such as angled conveyor belts.

The geared motors can be used for equipment group I category M2 and equipment group II in zone 1/21 and 2/22 explosion hazard areas.
