AMA Aluminium Motor

AMA Aluminium multi-mount motor


This range of aluminium 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.


IE1 = Standard Efficiency

Main specifications:


All AMA 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, B14S, B14L B35, B34S and B34L.
