{adinserter Internal_left}It has been all dry theory in the Brushless DC (BLDC) motor with Arduino series up to this point. This is where it gets to be more fun. If you’ve just arrived, please check out the previous two installments:

1. Driving a three-phase brushless DC motor with Arduino – Part 1. Theory
2. Brushless DC (BLDC) motor with Arduino – Part 2. Circuit and Software

In this final part of the trilogy I am describing the hardware part of the stroboscope project and the making of the zoetrope animations themselves, in hopes that my visitors can take this further and come up with their own animations, which I would absolutely love to see. More details below! Read the rest of this entry »

{adinserter Internal_left}In this post I will describe the hardware and the software part of a project involving the use of BLDC (Brushless DC) motor salvaged from a broken XBox 360. This is a second installment in the series of posts related to Arduino and brushless DC motors. Please see the first part for a bit of info on the theory behind the commutation sequence. Once you understand the commutation sequence for the particular design of the BLDC motor, the circuit design for the BLDC driver becomes pretty clear. It is not much different from a bipolar stepper driver in that we need the be able to both source and sink current at all ends of the windings, except of course in this case there are only three ends whereas the bipolar stepper has four.
