The low-voltage motors are available in various energy efficiency classes depending on the requirements. Our product range of IEC standard motors includes outputs from 0.09 kW to 400 kW. The relationship between size and motor power is defined in EN 50347. The decisive factor for our customers is which speed/power combination is required. We will be happy to help you select the right motor for your application. Up to size 132, the motors are generally produced with an aluminum housing and from size 160 the housing is made of grey cast iron. Of course, there are exceptions here too; we also have smaller motors in cast iron - some of them directly from stock. Contact us with the details and we will recommend a solution tailored to your application.
