Can a 555 timer be used to control a brushless DC motor with the help of an IC?

AI Thread Summary
A 555 timer can potentially be used to control a brushless DC motor with the help of an integrated circuit (IC), as referenced in a provided Microchip document. The discussion highlights the need for a circuit diagram to connect the 555 timer with the motor control IC. Participants suggest searching for resources on generating PWM signals using a 555 timer, emphasizing that the best solution depends on specific project requirements. There is also a recommendation to consider using a low-cost microcontroller instead of a 555 timer for more modern applications. Overall, further information about the project is needed to provide tailored guidance.

I have seen a link in this forum http://ww1.microchip.com/downloads/en/DeviceDoc/22263A.pdf

that denotes an IC to control a brushless DC motor. How to connect it with a 555 timer? Can anyone help me with the entire circuit diagram? Thanks in advance.

Thanks for the post! Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?
 
There are numerous sources of info for creating a PWM signal from a 555 - Google " 555 PWM" -- since the best solution for your case can have many factors - it would be difficult to give a clear answer / guidance otherwise. If this is a very simple case - then the simplest 555 solution will work. -
 
Need more information on what you are doing. Why are you locked into a 555 timer? Have you considered a low cost MCU from Microchip. I grew up on 555's (came out in 1970's), but there are other options in 2014.
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
