hello friends in small Bush DC motor if there are odd number of commutation segments then odd number of coil.... I have doubt regarding how to calculate switching current(reverse current value by commutation system) through one particular coil in DC motor.....coz we can't take total current flowing through motor as a switching current(reverse current by commutation system) because brushes divide the coil in two loops ..please help me regarding this..thanks
