Nothing good happen.As art said if voltage is low & frequency is low it would do just that to the point you could see happen.At most nominal world frequencies of 50/60HZ it will do this violently.Realize in this case your acceleration would be based voltage over time applied & in a sine wave this time to full voltage is very,very short.I would not recommend this connection.my above answer is based on theory but practically it will run.

depends if it is dc shunt motor it will not work but if its a dc series motor it might
