I'm not sure a bandsaw of this size needs this much motor, but since I have it, I'll try to use it. The motor appears to be 5HP 3Phase, and probably 1730RPM. It is old enough that I can't...

After 6 weeks the motor failed, the installer measured the voltage of the 3 phases which at the time were P1-237v P2-250v P3-233v and suggested this was the likely cause...

    Can a 3 phase motor that is running on single phase have 2 directions?

    I am needing to know if this wiring diagram is showing a few things: 1: Does this show a 3 phase to single phase conversion? 2: Does this show that the motor can turn in 2 directions with the same internal wiring if you toggle the SPDT switch?

    We have some shunt-wound DC motors that are used are servos (so operate over a big speed range and in all 4 quadrants, motor and generator both directions) and one of them (0.25kW) has gone "lumpy". My suspicion is the armatures has some open winding(s) so the speed/voltage profile changes as it...
