Flameproof Motors with Brake

Flameproof Motors with Brake

 

The installation of electric motors where flammable products are continuously handled, processed or storaged must comply with the most demanding safety standards in order to guarantee life protection, machines and environment. Following to highest safety standards, WEG explosion-proof motors (W21Xd) integrate the high performance of the brakes. An effective solution for equipment where fast safety stops are required, as well as precise positioning with safety in hazardous areas such as Zone 1 and Zone 2.

 

Technical characteristics:

  • output: 2,2 to 18,5 kW;
  • number of poles: 2, 4, 6 and 8;
  • frequency: 50 Hz;
  • voltage: 380–415/660 V;
  • frames: 132 S to 160 L;
  • color: RAL 5009 – blue.
 
 
 
 

Features:

  • high performance braking system ensures quick and safe stops and accurate load positioning and requires low maintenance;
  • manual brake release gives possibility to keep the motor free during emergency situations or whenever necessary;
  • modern flame retention system with robust frame, endshields and T-box let avoid flame propagation from inside the motor to the external side, guaranteeing safety life protection, machines and environment;
  • W3SealR sealing system and IPW66 degree of protection against the ingress of contaminants inside the motor frame;
  • additional name plate lets easy identification of the motors in the factory and traceability;
  • painting plan for severe environments;
  • motor suitable to operate in hazardous locations classified as zones 1 and 2;
  • WISER insulation system Increases stator electrical strength and allows the motor operation by frequency inverters, without damage by voltage peaks
 

Applications: pumps, compressors, fans, blowers, conveyors and other sever duty applications in explosive atmospheres classified as Zones 1 and 2, gas groups IIA or IIB.
