Porter cable 86902 spindle

[terry1956]

Hi out there. I have been looking for information on the Porter cable 86902 spindle. Not been able to find anything useful at all. My problem is that I don’t know if the motor works or not. There are four wires coming from the motor. A blue, brown and two earth wires. The motor is 240v. I don’t know how to wire the motor to test it. Or if indeed it works how to adjust the speed of the motor. ( there is no Denford boards in the machine ). So my questions are. Can anyone inform me how to wire the motor. Is there a way of controlling the speed. Or is there a replacement complete spindle that will fit into the carrier. Please bear in mind I am in the uk. Thanks

It's brushed so it'll be a universal motor and you can get speed controllers for them on the likes of ebay. Regarding the wires the brown should be live, the blue neutral, and you know the earths so you could wire a plug onto it and test with mains voltage which will give you full speed if it works.

I have posted up the connection info for the sprint speed controller and other manuals in the starturn section as it is the same controller.

The sprint outputs DC as far as i know and uses a 0-10v input to set the output. So the PC router runs DC on the denford machines. Don't trust the cable colours as the PC router is American and they have different colours. If i get chance ill look at mine, I would have thought it was in the manuals though. Ive not worked on a 2600, only the earlier microrouters.
