AMA Aluminium Motor

AMA-IE3 Aluminium multi-mount motor

This range of aluminium IE3 premium efficiency multi-mount motors are suitable for many different industrial applications, including fans and pumps. The multi-mount design enables the feet to be removed or moved to provide left, right or top terminal box configurations.


The European directive 98/34/EC calls for the introduction of IE2 motors from June 16th 2011 and IE3 motors from January 1st 2015.

IE3 = Premium efficiency.

Main specifications:

 

All AMA-IE3 motors are manufactured in accordance with IEC 34-1/9

The bearings are maintenance free lubricated with lithium-based grease

Motors are fitted with V-seals

Windings are vacuum pressure impregnated and made of high quality insulated wire and insulation material. The impregnation is an evaporation free process, suitable for tropical climate zones.

The rotors are dynamically balanced with half key, in accordance with IEC 34-14, class N (Normal)

Overload capability, in compliance with IEC 34, 1.5 times the rated current for 2 minutes and 1.6 times the rated torque for 15 seconds.

Mounting is available in B3, B5, and B35.
