I Wired it up and tested by bridging the wires and plugging it in when it's all back together and the motor runs at full speed. The test revealed that the foot controller wire was damaged and broken, so was replaced with a new lead. I carefully removed the windings, cut the insulation off, then put on some heat shrink insulation, which was shrunk with a soldering iron before I reassembled the motor. The motor had to be completely disassembled to remove the capacitor (which doesn't have to be replaced), and I also found that the field winding insulation was cracked in three places (one was at the motor housing). Plugging it in would have blown the circuit breaker. The excellent Wernard motor had some issues: The capacitor (inside the motor housing) was original (the only one I've ever seen in these motors), and just under what you can see in the photo the wires were bare and rubbing against the motor housing.Ĭapacitor is the silver thing at the top. It was also missing the foot controller, but it came with manuals and pattern cams! I was up for the challenge and have loads of the original foot controller. The round rubber belt was broken, but it was so neglected that this was the least of its problems. It had obviously not been used for years.
