I am about to venture into a new project and wanted to power it with this motor and VFD pictured.

The VFD, I am assuming that I can get most info online later when required.
Just asking if its going to be compatiable with my choice of motor?

The motor is really where I need the help.
I'm in Australia which may influence who can comment best!!!

The motor came out of a paper shredder and has a reduction drive which is just what I need.
Looking at the terminal box on the motor there are way more wires there than I'm use to and I am not sure how to handle them without explanation.

I am assuming at this point it is a single phase motor and guessing that it had some controller that I dont have and never saw that reversed it or gave it several speeds, but that is all speculation on my part.

Can anybody knowledgeable, please get some discussion going with regard to how I power this motor just to run.

 

Hi fifty, if it is a single phase motor a standard VFD won't work. A standard VFD is a 3 phase item. They do make some single phase VFDs but they are rare and pricey if you find one. Do you know the motor frame type? If so you may be able to find a three phase motor to replace the single phase with. Motors within a frame size usually have similar shaft and other dimensions.

 

Also 1ph VFD's are not that popular or prevalent due to the fact they often drop out of run at low RPM's.
Possibly sell the motor you have and purchase a 230v 3ph?
You can use 1ph supply up to ~5HP for VFD power.

Max wont be that lower speed if the motor is geared first.

Shortbus, the VFD is in the pictures posted and is a sigle phase, it says it fon the tage and is made in the UK, sold worldwide. Wont be running such lpw rpm since the motor is geared...

If you can run close to 50hz -60hz then may not be an issue.

Yes, it will just be for fine tuning as one of the functions of this project will to be rotating for automatic welding hence precise speed is required.

 

I can confirm my motor is a single phase unit and just needs a capacitor for it to run.
I've mail ordered a capacitor so I await its arrival and hopefully I will have rotation under its own power soon.
Next step will be to figure out how to connect the VFD.
I am assuming it will be a lot easier than my last experience with that Chinese Folinn VFD, that was a nightmare to setup and still to this day is a disappointment although it does run...

Last time I built my machine first and then struggled with power source issues.
This time I wont lift a finger until I have all my powersource issues behind me.

 

If it is 30uF per the plate, I assume you ordered motor start rated version!
Hopefully NOT Chinese origin?
They have a bad reputation on durability.

 

Italian, I think...
Fingers crossed it will out last me.

I have a question about what your doing. Why such a large HP motor? Are your weld pieces really heavy? With both a high HP motor and a gear drive your going to have plenty of torque .

 

I use what I find cheap.
This motor cost me $20 and the VFD $50.
Where I live, most of this stuff costs much more even though it is 2nd hand and still not sure if it is worn out.

 

Many welding rotator's just use a DC motor like a car wiper motor and a roller chain.

 

On this ocassion, this is a Frank Sinatra project...

That was my first guess.

 

motor and drive seem to match and should work. i don't see that motor going to low speeds though since at lower frequencies startup capacitor value may not work too well and of course cooling becomes an issue. as someone working with robots, i see turn tables and positioners all the time. but those are servo controlled as an external axis. but i am not quite sure what is the goal in this case. even though welding is to be automated, there was no mention of the actual system.

 

The motors secondary purpose is a rotating welding table lets call it, however the primary purpose is to rotate steel car rim so that they can be cut into call it halves and have widening bands added.
That process I expect will require more HP than for the welding rotation.
Nevertheless it is what I have so I will run with it.
Since the drive is gearbox reduced plus chain and spocket reduced I dont anticipate the motor to ever need to run at low rpm and the VFD will used more for the fine tuning of motor speed ...

 

Well got the capacitor that I needed , mailman around here is pretty darn slow.
Did a mockup and test and all worked well, so I went ahead and hooked it up for good.
So now my motor is powered up and works a treat.
I could not be happier.

Time to move on to the non electrical stuff for now and then once the motor is mounted I will attempt to set up the VFD.
