Repairing & Rewinding Squirrel Cage Motors

A team of E-motor experts at Elma’s service department is able to repair, overhaul and service almost any type of three phase E-motor or generator. Elma Services has over 80 year experience in these disciplines. In the same way our motor engineers are professionals when it comes to completely rewinding electrical motors.

Guidelines efficiency class

With the old guidelines, e-motors were classified by efficiency. The efficiency of a motor was indicated by the designations Eff1, Eff2 and EFF3. Eff1 was the category for e-motors with the highest efficiency. Hence a logic class for a higher efficiency became impossible.

The new European directive has solved this problems. The directive is based up on the IEC 60034-30 classifying the efficiency of electric motors with class IE1 (outside EU), IE2 (combined with a VFD), IE3 (standard) and IE4 (super premium).

The motors with IE1 class are suitable for applications that are deployed outside of Europe, for instance marine installations. Only under certain circumstances the IE1 motors can be used in Europe.

Elma Motors is capable of supplying specific and/or customized EM1 (IE1), EM2 (IE2) and EM4 (IE4) motors on request. Please, contact us to find out the options!
