Electric Motors 1MA7

1MA7 Electric MotorThree-phase, low-voltage asynchronous squirrel-cage motors in secured manufacturing with an aluminum frame.

Explosion-proof manufacturing: secured manufacturing EEx e II T1, T2 or T3.

Three-phase asynchronous motors in secured manufacturing are designed for these passive environments:

  • Risk of the fire of flammables and flammable liquids
  • Risk of the explosion of explosives specified in ČSN 332310 and ČSN 332320
  • 1MA7 motors can be used in zone 2
