I have been given a motor by a mate, it is a Carpanelli MM63b2 230v AC .25Kw 2820rpm.
It is dated 25/3/09 and looks like new. It works beautifully, smooth and quiet and is just the job for a Woodlathe I am planning to build.
I plan to have speed control on the lathe and maybe a readout of the speed. I have built a previous rpm meter for a machine before using a Pic micro and a light sensor etc but this motor has something which I may be able to use for that! IF I can figure out what the motor has in place?
Inside the motor's connection box beside the normal mains in connectors is a small hole which is plugged with sponge. Two thin wires go through this, one red and one blue. They seem to be going to the bearing end part of the motor. I would usually just split the motor to discover what they go to but I would rather not as the motor is so good!
I have measured across the wires and get 71 ohms whether the motor is spinning or not so I am wondering what they go to and how to test any theories as to what they could go to?
Any ideas would be appreciated as stripping the lotor is a last resort.
Thanks, Al
