Hi everyone I am looking to upgrade the motor on my dust collector in my shop to allow me to adjust the rpm of the motor based on which machine is running. Currently it’s a 2 hp 60hz motor, but is single speed and has a rpm of around 1500. I would like to get a motor that would work in the 3000+ range and work with a vfd. Also is does any one have any recommendations for low cost and easy to learn PLCs?

Edit: I currently have a vfd that I would like to use but it outputs 400hz.

I'm working toward my Level 2 and got tired of bouncing between PDFs to drill the written test, so I built a little study site and figured the rest of you might get use out of it too.

What's in it:

• Both certs. Full NAR L2 pool (100 Qs) and full Tripoli L2 pool (108 Qs), transcribed from the official 2020/2022 study guides.
• Real exam simulation. Practice mode matches the actual exam — same section mix, question count, and pass threshold (NAR 35/40, Tripoli 45/50). Random draw each time so retakes aren't the same test.
• Every answer explained. Each question shows the correct answer, the official rationale, and the NFPA 1127 / FAR 101 / TUSC reference so you can go read the source.
• Quiz + flashcard modes for grinding a single section (regs, motor designations, stability, safety code, etc.), and a searchable study guide with all questions visible.

It's completely free, no account, no ads, no tracking — your progress just lives in your browser. I'm not affiliated with NAR or TRA; it's an unofficial study aid, so always double-check against the current official study guide before you sit the real exam (the question pools do get revised).

Would love feedback — if you spot a wrong answer or a question that's drifted from the current guide, tell me and I'll fix it. Good luck to anyone testing this season.

Hey everyone i have created a tracker app for the egg timer telemetry and any standard nema gps, just plug in a serial device to a laptop and select the com port, works on mac, windows, Linux is untested
