AI Thread Summary
Using a single small motor to spin multiple devices can be achieved through a belt system, which is a common mechanical solution. This method allows for the distribution of power from one motor to several devices effectively. However, for optimal airflow and performance, it's often recommended to use one motor per device, especially for fans. Electrical power transfer is generally more efficient than mechanical systems like belts or gears. Overall, the choice between a single motor with a belt system or multiple motors depends on the specific application and desired performance.

Hello guys. I'am new here and i have a question. how can i use a small motor to spin several small devices? Thank you.

that doesn't really make much sense to me.

If you want max airflow, then you'd be best off sizing 1 fan to be as large as possible given the motor size/power.

If you want operate several small fans in different locations, then you should have a small motor for each one. The motor is always going to be smaller than the fan blades, and transferring power electrically is much easier than any system of belts or gears.
 
thanks Mrparkle for your reply. i meant in a small scale. how can i use one motor to spin several devices, it doesn't matter if it's a fan or something else.
 
a belt system is a pretty common answer. just look at the front of most cars for an example.
 
Here's how they used to do it, in the past.

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...
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...
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...
