Not really. The voltage and frequency are strictly tied to the rpm. If you spin it at just over synchronous speed, then you get essentially normal AC voltage and frequency. To get more voltage, you have to spin it faster -- and the frequency goes up, too. -- Lee A. Hart Ring the bells that still can ring 814 8th Ave. N.
