WEG Metric Motors - General Purpose and ATEX

Product catalog summary
General Overview: The document outlines the specifications and features of WEG Metric Motors, focusing on general-purpose and ATEX motors designed according to European IEC34 and IEC79 standards for industrial applications.
Specifications: These motors operate at 60 Hz with a 1.15 service factor and 50 Hz with a 1.0 service factor. They include Class F insulation with Class H impregnation resin and magnet wire, regreasable ball bearings for frames 160 and up, and a gasketed conduit box. They are suitable for Class I, Div. 2, Groups A, B, C & D – T3, and Class II, Div 2, Groups F & G – T3C environments.
Design Features: The motors feature an optimized ventilation system for cooler operation and reduced noise, a solid base to minimize vibration, and frames 225 and up can be converted between F1, F2, and F3 configurations. Aluminum frames have removable feet for easy conversion.
Performance: The motors are inverter rated with a 1000:1 variable torque and 12:1 constant torque for IE3 models, while IE2 models have a 10:1 VT and 4:1 CT rating. They offer a 1.25 service factor for 60 Hz operation (IE3) and 1.15 for IE2.
Product Range: Various models are listed with specifications such as horsepower, kilowatts, RPM, frame size, catalog number, list price, shipping weight, service factor, full load amps at 415V, full load efficiency, and dimensions. Voltage options include 460//220-240/380-415 and others.
Conclusion: WEG Metric Motors provide robust and versatile solutions for industrial applications, emphasizing efficiency, adaptability, and compliance with international standards.

Valid since March of 1996, this European Directive is mandatory since July 2003. If provides a classification for motors into areas containing explosive atmospheres. More than product specification, the present Directive gives special attention to the production process including design, production itself and sale. The certification for the system is provided together with the product certification. ATEX Directive 94/9/EC also classifies the equipment to operate in explosive atmospheres into groups and categories following the same classificiation basis used by CENELEC. notified body responsible...
