| pycoed:
This bloke's Youtube channel may help? |
| John Rudd:
An informative video, but its aimed at universal motors rather than poly phase induction motors. |
| awemawson:
An excellent well presented video - extremely clear :thumbup: |
| RussellT:
Thanks for all the thoughts and advice. :nrocks: I've seen a few YouTube videos on washing machine motors but none on motors like these. One of the interesting things is the motor speed sensor - interesting because the speed of a 3 phase motor should be fixed by the frequency - so there is presumably some feedback - possible for acceleration. I think that makes hacking the original drive boards extremely difficult - well beyond me anyway. :scratch: :( It would probably be easier to reproduce the output stage of the drive board and control it with a microcontroller. It might be possible to buy an off the shelf drive. I don't have any immediate use for these so they may yet go to the scrap man. Russell |

Russell --- End quote --- Russell, You're right about the speed being governed by the frequency but the drive can vary the frequency and phasing to give you variable speed and direction. Phil. |
