Electric Motors AOM, AVM, AKM

AOM Electric MotorsExplosion-proof, three-phase, low-voltage asynchronous squirrel-cage motors of gray iron.

Explosion-proof, three-phase asynchronous squirrel-cage motors, the AOM, AVM, AKM production line, are designed for applications in areas with the possible occurrence of an explosive atmosphere created by gases, vapors or mist (zone 1).

Explosion-proof manufacturing

  • For axial size 71MK to 160L: EEx d II CT4 (firm closure)
  • For axial size 180M to 200L: EEx d II B+H2 T4 (firm closure)
