Progressive and raised power motors are designed with the same idea. Both series have one size larger frame power compared to normal motor size and power. Progressive series frame differ from IEC design. The frames of the raised power series are in accordance with IEC.

When searching for a suitable solution in confined spaces and the standard motor has been found to be too large, VEM can provide at least these two power-intensive series to choose from.
