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.
