What is the relationshipp between motor speed and average value of the armature input voltage, in a small electric motor controlled by Pulse-Width-Modulation( PWM) ?
Is it correct that by increasing the duty cycle of PWM ( the average time the motor is switched on) , we can only increase its average speed. But if we want to increase its maximum speed possible, we have to increase the armature input voltage, because Angular Velocity (w)= Vinput/(k*magnetic flux)?
