Abstract :
WHEN NETWORK THEORY is used, the analysis of the commutating machine differs from that of the noncommutating machine in that a new transient is initiated as the commutator segments enter or leave the brush contact area. In establishing the equations of operation, each interval of time during which no switching occurs is considered. As in the analysis of the noncommutating machine, the first step is that of establishing a connection diagram of the machine for the interval of time under consideration. When the general condition of q1 and q2 coils in each commutating zone is considered, the connection diagram is applicable to all intervals. The inductances are determined as a function of time from a second diagram showing the physical orientation of the elements as a function of rotor position.
