Patent
Electronically commutated motor has arrangement that alters duty ratio of bridge control PWM signal depending on motor parameters to reduce current generated by motor if braking current exceeds threshold
TL;DR: In this article, the duty ratio of a PWM signal controlling the bridge is adjusted depending on at least one motor parameter to reduce the current generated by the motor if the braking current exceeds a defined value.
