Easily Controlling High Current on Our Linear Synchronous Motors

As we continue our journey to design a Linear Synchronous Motors, we realize that a lot of current is needed for this to function. Controlling the electromagnets with a sine wave AND using digital logic to do this can be intimidating. See how using pulse width modulation and transistors arranged as an H-Bridge can cross this gap.

Finally, we will come face to face with a foe – flyback voltage. This foe can fry your circuit boards lickety-split if you aren’t careful.
