Two speed motors allow adjustment of the power consumed according to the needs of the application. This permits significant energy savings and a reduction in CO2 emissions by lowering motor speeds to minimise power consumption.
AM/AMV Series – Pole change:
Also referred to as Dahlander is a two speed motor that offers a 1:2 speed switching (example 2/4, 4/8 etc.). There are two types of internal connection of the winding: star connection or delta connection. These motors are designed for a direct mains start-up and are of single-voltage.
