Hi, I have a scroll saw fitted with a 240v 85w motor. The motor runs very slowly, it is not the machine binding. Any suggestions on what to look for or how I can check it? I have thought of simply replacing it but the only type of motor that I can find is a sewing machine motor but they run at 6000rpm which is a tad fast for a scroll saw. Also I want to do it as cheaply as possible. Thanks, Norman |

These simple motors have a start/run capacitor to get them going Looks like the motor start capacitor is dying...Mend it with a new one... Should have a small value of a couple of MicroFarads or so but make sure it is AC rated... |

Thanks for the quick reply, I did wonder about the capacitor. Is there any way to test it? I have a digital multi meter. |
