Thanks Ian, I been trying to run a brushless motor I took out of a washing machine, Ive invested quite a bit on this project but its beginning to look like its not going to get of the ground. I cant get all the info needed, even the pc that Im going to use to drive it may not be fast enough cos...

I have not had the opportunity to measure any of the voltages supplying this stator, Im simply going by info picked up here and there. It is a 4 pin connector and this is a more updated version of the Paykel motor. It has been really difficult to get any spec on this particular engine but Im...

I dont know how much current, its always an unknown factor. Thanks for the circuit u presented and it did cross my mind only that I found out that the lpt port will only tolerate a certain type of voltage. Its best to take voltage from a pin on the port and regulate it back into the port.

Thanks for ur idea, the sensor on the motor will have a 15v independent power supply coming from a voltage regulator. As per the current it will draw, I dont know. Current rating always seems to be an unknown in most of my circuits cos practical is different from theory. The sensor is equipped...

Using com ports would require a lot of extra hardware, Its a bare bones project.

Thanks for showing effort but u did not grasp my post too well. Try and relax when reading the posts, if I did not have a parallel port on the old 386 I would not be trying to send info to it. The post is not asking for software to read the port, it is requesting for a circuit that can safely...

Good advice but it sounds scary, I would have loved a circuit that incorporates a optocoupler so that the Hall effect circuit and the pc circuit are isolated from each other.

Yes, there are many circuits reading from these but barely any circuits sending info back to them

I wish it was $3

Hi guys, thanks for all the responses. I think the best ones were the ones that made mention of the assembler language though thats just too stressful, I think I will stick to msdos and qbasic for now. I'd have thought that Windows did away with DOS long time ago so it would had been nice for me...

Thanks, my motors winding is a star but I will check the links u sent

Wow, thanks for that, I already have a large capacitor ready for the rectified power and Im planning to drive the IGBT's with 240v dc but on my former plans, I assumed that DC would be produced at the motor itself but from your info, it appears it will be AC. If Ac enters the motor coils, I will...
