| brushless dc motor conversion?? |
| << < (3/4) > >> |
| John Stevenson:
Anyone read the whole of the post in the Keeling link on brushless motors ? Seems that there are issues with the driver boards not working. |
| John Rudd:
I've just finished reading the full thread..... Seems there are problems with the driver board that have not yet been resolved. While it appears that resolution is close, the board may need reworking and wont be available until the year end... That's the message I get....... |

Have not been on the site for some time and only used it for information. Here is another one directly from a manufacturer http://www.adlee.com/brushless_dc_motor_with_ac_driver.htm I have only used these sites for info when I was developing a low speed spindle for my router. Allthou great variable speed propultion systems the cost in the end made me use 3phase AC with vector VFD in my design, not built yet as I am having lathe problems :bang:. Abraham |

(obviously leaving the earth intact) Are you sure that you need to reverse the direction off the motor? When I did my belt drive conversion I thought that my motor needed to be reversed, but it turned out that it didn't.

My sieg lathe used to give little electric shocks. it came with a funny looking plug and ran through an adapter, i changed the plug and found NO earth!!! |
