A range of "Progressive" motors from AEG Electric Motors enables equipment manufacturers and end users to achieve higher outputs from comparable IEC frame size machines.

A range of "Progressive" motors from AEG Electric Motors enables equipment manufacturers and end users to achieve higher outputs from comparable IEC frame size machines.

The motors are ideal for manufacturers that have restricted space envelopes, weight restrictions or simply want to be more competitive.

Directly interchangeable with motors of similar frame sizes, these AEG three-phase motors make possible for engineers to both minimise space requirements and reduce weight.

They are available as two-, four- and six-pole units As an example, the highest output from a standard IEC132 frame two-pole motor is 7.5kW; a comparable AEG progressive motor can double this (15kW).

Similarly, a 160 frame four-pole AEG progressive motor can produce 22kW, whereas a standard IEC machine offers 15kW.

Progressive two-pole motors are available in frame sizes from 63 to 180 with powers up to 30kW; four-pole units range from 63 to 250 with ratings up to 75kW; and six-pole machines go from 100 to 132 and 7.5kW.

The increased output from the motors is made possible by extending the internal lamination pack and building in more active material.

Some of the motors use the class F temperature rise available from class F insulation.

The multi-voltage input of 380-420V 50Hz/440-480V 60Hz is unaffected and still available.
