System EC



The EC System, used in all Nilfisk-ALTO ATEX ZONE 22 vacuums, is a single-phase drive system developed with an electronically commutated direct current motor. The motor is electronically controlled, making carbon brushes unnecessary. 



Advantages

  • Collectorless motor - carbon brushes unnecessary
  • Easier start
  • Operation without wear and tear
  • No sparks
  • Life of the motor is approximately 10 times higher than universal collector motors
  • Free of ignitable sources, therefore suitable for use in ATEX ZONE 22 applications
  • With overload protection for motor and electronics
  • A real alternative to 3-phase vacuums can be realised in the form of a much smaller and less expensive machine
