Can the motor on the electric drill be changed into a generator?
On the efficiency of well naturally than the original motor state is low, this is because the internal resistance of the power supply will be higher than the professional electric spark generator, and the commutator also makes as generator load capability.
Can! To be a DC generator, but the stator magnetic field winding from the series to shunt and do with excitation and excitation control device (also can not change directly series excited DC generator excitation control, but not too easy). The output DC voltage is lower than the original value of the armature winding. Then the best conditions of rewind, change the current excitation voltage for excitation.
