Web30 mrt. 2024 · The VFD needs to set the voltage threshold at which DBR should be enabled. This value should be set after careful analysis of the … WebAccording to the speed formula, speed = time (60 seconds) × frequency (50Hz) divided by the number of pole pairs. Here is a sample of ATO 200w brushless DC motor. The motor's rated speed is 3000 rpm, the pole pairs is (3000 rpm)/ (60 seconds × 50Hz)=1. That is to say, this motor has two poles. Selection of VFD Power.
