Abstract :
THE MANY important military, industrial, and domestic applications of commutator machines make it necessary that designers know the commutating ability of these machines. For machines using commutating poles within their range of effectiveness, the commutation behavior can be forecast with reasonable accuracy. However, where the varying resistance of the brush-to-bar contact is depended upon to control the commutation, that is, resistance commutation, there is a need for fundamental design information on which may be based calculations of commutation performance from circuit data.
