How you can make a motor?

Answer 1

This is just to give you an idea on how to get started not the complete instruction.

To have better understanding check out how BLDC motor works in YouTube.Then you find below something relevant.

To make a motor(to learn how it works) you need to create a stator which on excitation creates a rotating magnetic field. It must spatially create a field as if north and south poles are rotating at some speed. To do this, you need make simple electromagnets (four) arranged 90 deg from one another. The electromagnets placed in opposite are connected in series. So now you have four wires comming out(2 phases) .Now phases are energized one by one with additional electonic circuitry. Stator is supplied with DC with aid of power semiconductor devices.

In the rotor part can have permanent magnet which will try to align itself such that north and south poles of the rotor(magnet) will try to align with rotating field. The rotor is pivoted at the center such that it is surrounded by stator poles.

By exciting the stator ,the rotor will eventually try to align itself and rotate.
