Imperative that you measure the resistance between all wires, so you can see how many windings and how they are connected inside. Some have a starter winding with a capacitor, some are DC, it could even be a stepper motor for all i know...

If there is a data plate on the motor you might google for some help, otherwise it's hard to say. Possibly there are some standardized colors.
Google could be your friend here too -- try something like "AC motor wire colors" -- maybe you'll get lucky.
Be aware that many AC motors require a special capacitor to get them started.

If it is an induction motor, it could be 4 pole, which in that case would be a poor choice for a bench grinder due to the lower rpm, 2 pole are traditionally used.
