VFD and AC Motor replacement project

[allenj20]

Anyone with a V2 machine want to take a couple of photos of the gas struts mounting setup so I can get an idea for that part of the project?

I am just curious how they fit all that into such a small package, where just about all other drive manufacturers need the room to put the large power supply usually associated with VFD and BLDC DC power supply?
Sensorless BLDC has been around for a while but that IS small for a VFD of that capacity?
It resembles more the appearance of a 3ph slow start.
Be nice to see some working applications?

I am not home right now or I would give you exactly what you want, but maybe these will do?





Feel free to poke around to see if there is something else useful:

Mikini 1610L | mcphill | Fotki.com, photo and video sharing made easy.

Thanks Mike that is helpful.

If anyone has the length and force of those shocks that would be helpful too.

The main black tube is 13in. and ~27mm in diameter, the bright metal piston extends 12in. and is ~16mm in diameter. I don't know how far the slender black piston extends but it makes up the difference when the Z is all the way up. The total extended length from center of ball joint to center of ball joint when Z is at maximum height is 31.25in. Don't know what the weight is, Phil would probably tell you if you asked him. Then you can simply take the weight difference between the 22lb BLDC and the new AC motor and add that to the weight rating of you struts. McMaster-Carr also has a nice selection of gas springs: McMaster-Carr

Thanks swath that's what I needed.

[allenj20]

Well the motor is here.

Unless I am mistaken (due to the perspective), Dat's a BIG motor!!!

[allenj20]

You are not mistaken. And it's from the MicroMax series. You can begin to see why I did not go with a 3HP motor it's bigger still of course. As it is this will only just fit I think.

I also ordered the gas struts yesterday from McMasterCarr I ordered 2 50lb struts for 100lbs total they have a 16 inch stroke and a max length of 35 inches.

The VFD should be here this week as well.

Unless I am mistaken (due to the perspective), Dat's a BIG motor!!!

What does that way?

[allenj20]

45 lbs

What does that way?

This thread is getting exciting! Thanks Allen, it gives me hope for a productive machine.
