Periodic pulse signal time duration determination method for electronically commutated motor, involves providing numerical value characterizing signal from period duration and signal pulse duration

摘要

The method has the period duration of the periodic signal determined at spaced intervals, with provision of a characteristic value for the signal pulse duration, combined with the period duration for determination of a numerical value characterizing the signal. Also included are Independent claims for the following: (a) an electric motor with a computer program for determining a numerical value for a periodic signal; (b) a device for determining a numerical value for the time duration of a periodic signal.
