I agree with Vman's general assessment; the motor can be wire directly to a plug. The only thing that you may want to add to the basic design would be an on/off switch; that way, with switch turned off, you can plug it in with relative safety and minimum risk when turning it on. If there are wires still on the motor, you need only strip the insulation back enough to connect the motor to your plug OR switch & plug and use wire nuts and electric tape. The more thought and effort you put into your design and build, the safer and more durable the finished product will be.
