lockridge test 1
This is an attempt to replicate the Lockridge device. So i used my radial motor with axial flux as a rotor, In this case i used only 1 pole with a counterweight on the other side, So the rotor receive 1 pulse per revolution and as it is quite heavy is acts also as a flywheel. The motor coil is air cored (no cogging) and has loiw impedance (0.2 ohms). The coil receive the juice from a cap which is fed by a DC power supply. The commutator is a Hall switch. So the coil is pulsed very strongly and shortly on some degree of rotation and all the rest of rotation is time to recharge the cap until the next pulsed discharge.. So the motor spins with almost constant input power on a large speed range. So now the try to replace the DC power supply by a generator ??? Just to say when i got to more than 35 volts at very low speed i destroyed the FET. I don’t know why (perhaps very strong back spike) . If any idea, i would appreciate Thank’s Laurent
