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.

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
