To all those watching- We had some mic issues filming this, but on our next video we have improved our audio greatly with some new mics and some changes to our post processing. Thanks for tuning in!
Thank you!! I'm wrapping up the video showing the board repair and HL-1 Startup- it may be a few weeks, but do stay tuned! Lots of big changes coming to the channel- moving forward Rocan Motor Company will be my full-time job, so plenty of content to come!
Thank you! I tallied it all up and the final cost was roughly $800 for everything. That includes just about everything except for the 4/0 quadruplex cable to connect it all. The motors were free as was the steel for the frame. 40hp rotary phase converters generally are $5000 or more, so overall I'm happy. A smaller unit can be built for much cheaper- the pulleys required for the large motor for example are roughly 25% of the cost, and the large contactor was another 25%.
Hey there, im diving into rotaty phase converters myself and i was wondering a few things First of all, rotary phase companies nowadys will advice you to use a “smart" converter. Do you think a balanced phase converter will work aswell as a smart phase converter ? Second of all, what is the wiring for the voltage display? Thank you fort the video
Yes! Once the main motor is started the idler is shut down. The control circuit is set up in such a way that if there is a power failure the entire unit will power down, so it is fail safe. Additionally, since the pulleys I am using are slightly different in size (6" vs 6.5"), I would be unable to run the idler and pony motor simultaneously.
Thank you Joe!! I say give it a shot with a smaller 3 phase motor. A phase converter this large is a bit daunting (and deadly), but the same principles apply to all 3 phase motors and with some research and planning you could have a working phase converter in a weekend. Also, it doesn't need to be expensive- local ads (marketplace, craigslist, etc) turn up free 3 phase motors and components all the time.
The bigger motor may have a threaded plug on the bottom side of the bearing bell ends that you greased. Take those bottom plugs out when greasing and the old grease and bearing wear particles will get pushed out of the motor.
I'll have to check! I appreciate the comment, I was looking for a second port/ for the grease to come out but didn't see one. Didn't cross my mind to look underneath. Thank you!
Do you leave the pony motor belt connected after start? Others I have seen use an idler pully connected to a lever so the belts can be slackened after start, think clutch.
I considered an electromagnetic clutch, similar to an AC compressor in a car, but ultimately opted to keep it simple and left the belt turning whenever the system runs. The losses are negligible.
Seems kind of silly to mount the pony motor the way you did when you could have mounted it to the frame along with the larger motor. I really enjoyed the electrical end of your project though.👍
I doubt you’ll ever pull more than 30 amps with your vf2. In my experience power requirements are over rated. Also with a properly designed phase converter, start-up with capacitors wouldn’t be a problem with a motor of this size.
I'm my testing of the VF-2SS so far I'd agree. Regarding the capacitor start, the current draw for a motor this size was in the 300 A range, supposedly, which I hadn't confirmed through any math of my own. That's for a brief moment of course, and likely okay, but I had the pony handy so this seemed simpler at the time.
1800rpm, 120/240vac, single phase, 1.5hp. I'm running it on 240vac in this setup. Its okay if there's a slight mismatch in speed- since the pulleys are slightly different in size after the idler motor starts it slows down the pony motor.

cant wait to see you fix those boards! very cool build

Very impressive, from a crusty old miller from the UK I wish you well
Thank you for the kind words!
This is great content keep it up!
I appreciate it! Comments like this really help to keep me motivated!
It clamps on the shaft? Awesome.
With remarkable force! Split collets are really great.
We built a pony motor start stand for a 30hp idler, currently only using a 10 hp idler. Very nice build.
quality video ! how much did it cost in total? thanks for sharing

Thank you fort the video
Do you still turn off your idler motor?
Yes! Once the main motor is started the idler is shut down. The control circuit is set up in such a way that if there is a power failure the entire unit will power down, so it is fail safe. Additionally, since the pulleys I am using are slightly different in size (6" vs 6.5"), I would be unable to run the idler and pony motor simultaneously.
Great vid buddy, I’d luv to be able to do something similar, but don’t have the confidence 🤙

Congratulations on the 3 phase. Excited to see you fix the Hass
Thank you! The lathe is up and running and we are working on the video showing the drive repair. Very exciting times for us!

I want to ask about your idler motor specification,
rotation speed? voltage?
thanks

Grate video and a nice big motor:)
Thank you Luke!
