Possibility of Using a Homopolar Generator as a Pulse Generator

A homopolar machine has been analyzed to ascertain whether it is possible to use it as a high-current, low-voltage pulse generator. A transient expression for the field flux has been deduced and the time constant determined. The effect of the eddy currents produced in the solid metal body of the machine has been included and an expression for the flux density due to eddy currents has been deduced, as well as an expression for the transient current in the magnetizing coil.
