Hi all, I am working on a project that has been using a bi-polar stepper motor as a generator. The former project involved moving the shaft back and forth a few degrees which made a normal DC motor impractical for use as a generator. However, recently we switched to storing energy in a flywheel, and the shaft rotates completely in a single direction. So I am wondering if a normal DC motor would make a better generator. when doing the conversion from a stepper motor to DC, we used 2 full bridge rectifiers which induces a small loss. the system we have devised is high torque, but low frequency, the motor shaft rotates at about 240 RPM I'm looking for some thoughts on this, and what type of motor might make a better generator.
