The motor is 0.75hp, roughly 0.5kW. |

I think the next steps for me are to get a list of parts together and maybe a wiring diagram, and pull the motor to check the configuration options. Thanks to all that have generously contributed to this thread. |

Regarding all the existing switch gear, I would ditch the lot when fitting the VFD. A modern rotary or toggle switch is easy to wire up for controlling motor direction. Thanks, I'll bear that in mind. Not sure what to replace the start/stop switch with though? I assume (having also noted Mr. Rimmer's comments above) this will need to be wired on the output side of the VFD unit and therefore compatible with the output voltage i.e. 3ph 230V?

Check the motor can be wired Delta 240v.
The rating plate suggests that it can be. Suppose I won't know for sure until I pull it out of the cabinet and have a look. |

Nice machine, but messy blockwork !!
Indeed! It was like that when I bought it! Edited By Kingofthehill on 10/05/2022 09:55:04 |

Hi Chris. Life long mountain biker. Doing less of it these days though due to the onset of middle age and associated decrepitude. Other than that, bit of paddle boarding and camping now and again. I find myself in the shed a bit more these days doing "projects". |

Not sure why the album rotated them, nor how I correct it. It seems a clunky tool (the photo album tool, not the lathe). Maybe it's just me? |

Thanks Pete for your thoughts. Point taken regards reverting back to 3 phase. I was just thinking that , should I decide to sell it, it may appeal to a wider audience if this was easily achievable. I dunno, probably overthinking it. I've attached a pic of one of the machines. The start/estop is quite modern, the fwd/rvs switch looks like it's original kit. Both can be seen clearly in the pic. Edit: No idea how the image upload tool works. Will post the pic when I've figured it out.

Evening.... Has anyone done this on this particular machine? I'm pretty sure that I understand the general requirements for achieving this but no doubt will ha e various questions regarding the utilisation of all of the existing switches and controls.
Intend to purchase a VFD and integrate this into the machine base cabinet with a potentiometer. Want to retain existing start/estop switch and reverse-stop-forward switch. What are the pitfalls?
Will probably wire so that there is a long flex cord and 240V three pin plug exiting the machine. Is there a way to wire this so that I can revert back to three phase using a switch (I understand that if the answer to this is yes, that there would need to be something funky going on to switch the wiring configuration over at the motor junction box).
Your comments gratefully received. |
