Schaltung und Verfahren zum Vermindern hoher Stromspitzen in Statorwicklungen

摘要

A circuit for minimizing the current spikes in through the stator coils in a brushless dc motor is disclosed. The circuit includes means (110) for comparing an input voltage to a feedback voltage, means (115,120) for integrating the output of said comparator, a stator drive circuit (140,150) for driving the stator in response to the integrated output of the comparator; and means (130,135) for selectively enabling and disabling the stator coil circuit and integrator means.
