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.
Standard Features
- 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
- Color: RAL 5009 - blue
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.
| Features | Benefits |
| Reduced surface temperature | Safety, prevents the ignition of combustible dust or fibers in contact with the motor |
| Conductive material fan | Safety, avoiding sparks that could cause the ignition of the combustible material present on the environment |
| Degree of protection IP66 | Protect against the ingress of contaminants inside the motor frame |
| Winding thermal protection | 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 peaks1) |
