Hi John, Thank you for the information, might have a go at rewinding the fields. Cheers. Abraham |
| John Rudd:
Just a thought, howxhave you connected the field coils? Originally, the coil ends would have been connected via the brushes and the other ends would have been your supply......so have you just joined the brush ends? 2 ohms seems low....., :scratch: |

Both fiels and the armature were in series. For the generator I have the fields in series and the armature separate. The fields are wound with fairly thick wire and do not seem to have a lot of turns. Abraham |

Abraham --- End quote --- So you need more turns, if the formers are such that you cant accomodate, then reduce the wire gauge...field strength is down to ampere-turns...you may need to experiment a little to achieve a decent output voltage... |

Thank's John, will try to wind a coil on a seperate former for testing, the way the formers are on the fields meens they have to be hand wound turn by turn. |
