2 Product Overview WEG is proud to announce and introduce the completion of the W22Xd Line of Flameproof Motors with 3 new frame sizes 560, 630 and 710. The Maia factory in Portual is the Centre of Excellence for the desin and manufacture of LV, MV and HV explosion proof induction motors, specially developed for OIL & GAS and MINING markets. With this rane extension up to frame size 710 and 4500 kw, WEG makes available a real lobal and comprehensive product portfolio accordin to the most demandin specifications coverin a lare variety of applications for hazardous area industries worldwide. This ultimate product comprises frame sizes 560, 630 and 710, which are the extension of the existin W22Xd Line and is the result of years of development plan that WEG named as W22X Project. Durin this development, a lot of simulation studies were undertaken with complementary experimental prototype tests always with the taret to et cooler and efficient motors. WEG has now a complete flameproof rane of motors startin in frame size 71 up to 710. The new motors are available in Medium and Hih Voltae from 2 up to 8 poles, 50/60 Hz. Low Voltae motors and other speeds are also available on request. The new motors will have a wide rane of options similar to the existin available in the W22Xd Line. The new frames are in a cuttin ede tubular coolin technoloy comparin with the ribbed frames technoloy base on the smaller frame sizes. The new frames have an incorporated air/air heat exchaner and manetic cores with radial and axial air ducts construction. This coolin principle is based on an external shaft fan that forces the cold air into the frame tubes and by two separate internal coolin chambers makin the hot air circulation for an efficient air/air heat exchaner over the frame tubes. The efficient coolin system was developed also to assure a low noise level and reduced mechanical losses. All the frame enclosures are in fabricated steel with stainless steel coolin tubes and cast iron terminal boxes ivin a final riid, reliable and a low maintenance cost motor, suitable for the most demandin applications. WEG adopted also modular principles of construction oin aainst the usual idea that bi machines must be tailor made and project oriented. This extension Line is now available with ATEX and IECEx certifications for Ex d(e) IIB T4 Gb (W22XdB versions). It is also foreseen the certification such for Ex d(e) IIC T4 Gb (W22XdC versions), Minin - Group I (W22XdM versions) and conductive dusts - Group III (W22XdBD and W22XdCD versions). Other reional certifications such as GOST, CCOE, INMETRO... will be available in the future. Product Certification tests are undertaken by INERIS (French Notified Body) INERIS is also the notified body that issues to W22Xd Line concept the ATEX / IECEx Product certificates. WEG production system is assessed and certified by Baseefa that issues the required QAN and QAR certificate. Medium Voltae - Outputs (kw) Frame 2P 4P 6P 8P Min. Max. Min. Max. Min. Max. Min.

temperature. For motors with increased safety terminal box, voltae and tolerances are limited by IEC 60079-7 Standards. The maximum voltae allowed for Ex e equipment is 10 kv ± 10%.

4 General Construction Electrical Features WEG flameproof motors are tested in accordance with EN/IEC that imposes a voltae drop supply of -10% for validation of the enclosure surface temperature. For motors with increased safety terminal box, voltae and tolerances are limited by IEC Standards. The maximum voltae allowed for Ex e equipment is 10 kv ± 10%. The W22Xd standard line voltaes are indicated on the followin table: Hih humidity can result in premature deterioration of the insulation system, therefore, for any ambient temperature with relative humidity above 95%, it is recommended to coat all internal components of the motor with an epoxy paintin, also known as tropicalization. As standard, the W22Xd motors have a tropicalized paintin and are equipped with: MV Voltae Rane 50 Hz Y 3,0 kv / Y 6,0 kv 60 Hz Y 4,16 kv Windins protection Medium and Hih voltae motors have two Pt-100 per phase (3 wires), connected in the auxiliary terminal box. HV 50 Hz Y 10,0 kv Unless otherwise specified, the rated power outputs shown refer to continuous duty operation S1, as per IEC and under the followin conditions: With ambient temperature rane from -20 C to +40 C With altitudes up to 1000 meters above sea level All motors are supplied with Class F insulation and Class B (80 K) temperature rise at normal operatin conditions. The insulation system for medium and hih voltae motors consists mainly of rectanular bare copper wire with mica and VPI insulation system. Medium and Hih Voltae standard motors are equipped with tubular space heaters of 230 V. Bearins protection Medium and Hih voltae motors have one Pt-100 per phase (3 wires), connected in the auxiliary terminal box. Motors for use with VSD WEG Flameproof motors are desined with re-inforced insulation to withstand harmonies due to VSD operation. Bearin currents are avoided by means of insulated bearins and roundin rins. For VSD operation motors, the speed ranes must be confirmed. Dependin on the operation speed, restriction may arise due to bearins/sleeve bearins maximum peripheral speed, from rotational parts or rotor natural frequencies. The followin tolerances are allowed in accordance with IEC Standards: Efficiency (η) Power factor Slip Startin current -15% (1-η) for Pnom 150 kw / -10% (1-η) for Pnom > 150 kw -1/6(1-cos η) Minimum 0,02 and Maximum 0,07 ± 20% for Pnom 1 kw ± 30% for Pnom < 1 kw +20% (without lower limit) Startin torque -15% +25% Breakdown torque -10% Moment of inertia ± 10% 4 Flameproof Motors
