Today I've discovered this video (ruclips.net/video/SzuZqyF08Go/видео.html) from @WalidIssaPlusE that has a LTSpice simulation of a buck converter. While the circuit is different than mine, the basic concepts can be seen through the simulated signals.
I need to change out my drill press motor. Which way should I go? 3 phase motor-I will need to convert my 220 v. line to a 3 phase using an inverter Or go D.C. with a D.C. motor,I will need to convert 120v A.C. to D.C. What are your thoughts professor? Keep up the good videos!
First off I'm not professor. A DC motor requires a suitable driver which usually requires speed feedback, so a tachometer would be necessary. On the other hand an AC asynchronous motor can be effectively driven by a VFD, no tacho required. DC motors often are chosen when high stall torque is needed, which is not the case of a drill press. A good vector VFD can make a proper AC motor to provide acceptable stall torque. Hope it'll help.
Great tutorial on Buck Converters! I am surprised such a simple setup can work. Super instructive!
Thank you.

what happened to the lathe...
It needs electronic parts, still working on them.
