I got wondering Brushless Motor vs conventional motor.
If I spin a regular motor consisting of a brush perm magnets I'll get a voltage out (obviously), but this is not the case for a Brushless motor...... But... here's what i was thinking, what If you could use a small battery to energize the magnetic field then spin the motor and use the energy from that to keep the second field powered?...
Would that be more or less efficient of producing energy than a conventional motor?
