Brushless dc motor theory
WebHard drive spindle motors often have 12 cogs, for example. However, for a relatively recent (~10 y.o or less) CD/DVD/Bluray spindle motor it’s pretty safe to assume 9 cogs/12 poles. This will be a crucial piece of information when we turn to the hardware and firmware implementation based on Arduino. See the next installment of this mini-series! WebA brushless DC motor, also known as synchronous DC motor, unlike brushed DC motors, do not have a commutator. The commutator in a brushless DC motor is replaced by an …
