W22Xtb - Dust Ignition Proof Motors
W22Xtb - Dust Ignition Proof Motors
The W22Xtb motor has been specially designed to maximize safety and quality of motors apllied in explosive atmospheres – Zone 21 (grain processing, cereals, textile fibers, powder coating, polymers, etc.). Reliability and safety is ensured at the presence of conductive dust suspension (cloud) or dust layer (up to 5 mm), according to IEC standards.
Technical characteristics:
- output: 0,12 to 450 kW;
- number of poles: 2, 4, 6 and 8;
- frequency: 50 Hz;
- voltage: 220–240/380–415 V (up to 100 L);
- 380–415/660 V (from 112 M and up);
- frames: 63 to 355A/B;
- colors: RAL 5009 – blue, RAL 6002 – green.
Features:
- reduced surface temperature prevents the ignition of combustible dust or fibers in contact with the motor;
- conductive material fan gives safety, avoiding sparks that could cause the ignition of the combustible material present on the environment;
- protect against the ingress of contaminants inside the motor frame (degree of protection IP66);
- winding thermal protection the motor at abnormal operating conditions, preserving the designed surface temperature;
- WISER insulation system increases stator electrical strength and allows the motor operation by frequency inverters, without damage by voltage peaks.
Applications: sugar refining plants, breweries, cement plants, textiles, pharmaceutical, chemical, agricultural process industries and other applications in explosive atmospheres classified as Zones 21 and 22.
