Why does a sewing machine motor overheat?

when a motor get hot to the touch it mean that its bushes is running dry ,you can try and oil shaft where it dissapear into casing leave for hour or so to ensure oil penetrate and try again only other way is strip motor clean bushes and shaft and hope windings are still ok,lubricate with thin white oil,if you can leave bushes in oil overnite if the motor run without pressing pedal it means that noise surpressor inside pedal is damaged ,take it out and throw away
