Consider a pwm connected to an amplifier that drives a dc motor that draws a maximum current of 5a. it is designed to have a duty cycle of 50% to obtain this current. the operating conditions are such that at equilibrium, the torque requirement is 1/5th (or 20%) of the starting torque. what percentage duty cycle is required to obtain this torque? what is the corresponding average current?
