First I have to apologize if I posted this in the wrong group. If so please direct me elsewhere. I recently purchased a 1/3 hp motor on EBay. The motor is new, even though it has been manufactured in 1983. I also verified this by looking at the brushes. I wired the power as directed in the instructions. I have wired several motors before so I can assure you this is not just a newbie wiring mistake. When plugged in the motor, it turns at less than 60 RPM even though it is rated at 1725. I can actually grab the shaft and stop it. Is this motor just bad from the factory? Is there a way to verify it? Is it possible that the wires are marked wrong? The shaft is free (not bound) the bearings are good. I also verified that it is not a gear motor. You can see the motor at the following link Ajax 1/3 hp AC Motor md. TDCG-13-115 -- RPM 1725
