The process of steering current through the appropriate motor windings in order to produce an output torque is called commutation. Before start-up, permanent-magnet 3-phase motors must have an absolute position value available for electrical commutation.
There are several solutions from HEIDENHAIN that make this possible, the first of which are absolute rotary encoders. Read more »
