How should I hook up this AC induction motor to generate electricity?

Hi all, 
I am trying to make a generator out of an old motor I have. It is a GE 208-230v, 1/4 hp, single phase, 980 RPM motor. Based on the wiring diagram, I’ve hooked up a capacitor (7.5 mf/370v). 
I’m spinning the rotor of the motor via a bicycle, and I’ve figured out the gear ratio so I know how fast I have to pedal to (hypothetically) generate electricity (that is, generate positive slip).
The problem is that I can’t seem to generate more than 0.7 v or so (AC). This is seemingly due to the electromagnets being not energized and hence not creating a magnetic field. I’ve tried a few things, so as flashing the motor with 12v DC current for a moment to try and energize the magnetic field.
My question is: how could I hook up this motor so that I can generate electricity via spinning the rotor?
As an aside, the motor works in the sense that I can connect it to 120 v AC power and the rotor spins. I only run it for a second or so though as I don’t want the low voltage to damage the motor.

Darren I am pretty sure the short answer is, you can't.To make a generator you need field coils and you don't have any here, or much possibility of accessing any.It would seem this motor has two windings as indicated by the Lo/Hi connections on the nameplate.  It's possible you could use one winding as a field winding.  With your meter, look at the resistance of the Lo / hi points to the common winding (pur/blu/wht) and you should find a middle point, which won't necessarily be the Pur/Blu/Wht wire..  Use the higher resistance one as your output.  Put 12V across the other winding (but check the resistance - you don't want more than about an amp here so make sure it's at least 12 ohms) and see what you get.I am assuming the lo/hi connections will be for low/high speed, it looks like a washing machine motor....You can also check the capacitor connections - one of them should have zero ohms resistance to one of the other wires, and the other will have an appreciable resistance.  Use the one with the lowest resistance  to one of the other wires as your field coil, with the same precautions as above.You should get something out of this, but whether you will get a workable generator I am not sure..  Let us know how you go.

This is a 60Hz AC induction motor, so look up how AC induction motors work. The capacitor provides a phase-shift to one of the stator windings, to convert the AC magnetic field to a rotating magnetic field in the stator, to produce torque. There is no commutator. Instead electromagnetic induction (same as between primary and secondary windings in a transformer) is used to induce AC current in the shorted rotor winding. Induction motors can be used as generators to add power to an existing power line: Look up "induction generator". Induction motors cannot be used as standalone generators, as they need an  external AC source to set the frequency of the 60 Hz and to induce current in the rotor. Note that the rated rotational speed of your motor is 980 RPM = 16 1/3 RPS, not a submultiple of 60 Hz. This non-submultiple-ness is called "slip", and is central to the operation of AC induction motors.The 0.7 VAC you get spinning the rotor is probably due to the residual DC magnetism of the iron in the rotor letting the motor act as a small rotating-field generator. Compare the frequency of your 0.7 VAC to the frequency of the shaft rotation.

Peter is right I think, my idea of putting DC as excitation on the capacitor or any winding will not work.

Have a look at this link  motor as generator, it is quite sensitive to the capacitor value. There are a number of references at the end of the document. Use Google scholar to chase them up.There is also a lot of other practical info on the web if you search for it.The observation has been made that there are different windings, you will need to sort out which you intend to use.Cheers,Richard

A correction to my previous post: Induction motors can be used as standalone induction generators. The article linked by Richard Gabric discusses the issues around startup excitation of the initial magnetism needed. The authors report that their generator's performance is sensitive to capacitor value, and also that the capacitor must be precharged from a DC source before connecting the capacitor to the already-rotating generator. Generator excitation refers to the source of the initial magnetic field needed for the rotation of the rotor to induce voltage in the stator.
