hello, i m new to this group.

i got to see ur name on the site online.

so, i thought gathering some information from u.

actually, i m an electrical engineering student and i m about to do a project on the conversion of single phase induction motor to generator.

so, for that purpose, we need to give excitation via capacitance and for that we have calculated the magnetising reactance and reactance of main and auxillary windings as well and given capacitance accordingly but still the voltage is not being generated.

so, i want to know whether the process i m going is not right or is there any other way i can convert single phase induction motor into generator without making it PMG(permanent magnet generator).

Plz do respond at aesthetic002@yahoo.com.

Good book for you:  SMITH, NIGEL - MOTORS AS GENERATORS FOR MICRO-HYDRO POWER

Yes that is probably the best reference.

Without more details of the motor it is impossible to form any opinion.

Single phase motors are particularly nasty for self excitation. Not all will self excite, especially small low efficiency ones. If you are at nominal speed just increase capacitance and see what happens, no reason to assume your calculations are near the mark, it is a very difficult thing to calculate.

If you get to the farad and nothing happens you have chosen a bad motor.

Just another thought, you will not likely manage to excite it from the start winding, forget that and try capacitors across the run winding. If you get it to go then some capacitance across the start winding may help but the capacitor needs to be directly across the winding, not where it is as a motor.
