Mid-Torque range AZ and ZZ

1,5 - 66 Nm, 500 - 5,000 rpm

AZ motors are closed outer runner motors with shaft

ZZ motors are closed outer runner motors with shaft and IEC mounting Domel has developed state-of-the-art motor construction, which offers the highest efficiency in compact size and lightweight motors with the use of non-rare earth, ferrite magnets. Efficiency motor + VFD can be up to 93%.

Domel’s PMS motors guarantee high energy savings and reduce payback time. Products comply with IE5 according to the new proposed Standard.

Our motors reduce operating costs by working at a very high level of efficiency within a wide speed and power range, significantly reducing total operational costs. Energy saving is our responsibility.
