All true guys,
With small motors of the type being discussed though.... Single Phase Induction Motors, there isnt a lot to worry about. If the motor is a Capacitor Start/Run type then you would need to replace these with new items of slightly different capacitance and in most cases this will cover it. Naturally, motors designed to run on 50Hz will run slightly faster with 60Hz supply but this is also not usually a problem. Depending on duty, a resulting reduction in torque may be a problem depending on how close the motor is to specific output requirements and by contrast, the actual output power increases slightly.
With any large industrial application motor though, all of the above needs to be thoroughly examined in order to re-rate the motor when used in an application where line voltage and frequency is other than what it was originally designed to use. Hope this is of some help....

Mal.
