Explosion-proof and ignition-proof electric motors

Simotics XP motors are electric motors for use in an environment where there is a risk that combustible vapours and gases will explode or that flammable dust will be ignited.
Power output from 0.06 to 500 kW.

Includes versions for the following conditions:

• 2G - Zone 1 (Gb)
  A zone where explosive vapours and gases occasionally occur

• 3G - Zone 2 (Gc)
  A zone where explosive vapours and gases are not present in normal operation, but if any such occurrence does happen, it is rare and short-term

• 2D - Zone 21 (Db)
  A zone where a cloud of flammable dust (including conductive dust) occasionally occurs

• 3D - Zone 22 (Dc)
  A zone where flammable dust is not present in normal operation, but if any such occurrence does happen, it is rare and short-term

Versions for Zone 0 (permanent occurrence of explosive gases) and Zone 20 (permanent occurrence of flammable dust) are not available.

Optionally, we also offer special explosion-proof motor designs (e.g. versions for mining operations).

General Features

• if the power is supplied from an inverter, a special motor configuration and certified winding thermal protection are required
• limited configuration options
  • limited modular superstructure variability compared to standard motors
  • limited opportunity for increased ambient temperatures
• ATEX certification for each motor
• standardised dimensions to ensure compatibility with other brands’ products
