A geared dc motor uses a 13 kHz PWM signal to control its speed. It uses a 12 V supply voltage and requires a minimum duty cycle of 15% to overcome frictional forces in the motor/gearbox and start the motor rotating. As the duty cycle is increased, the motor speed follows a linear relationship with this PWM signal up to the maximum angular velocity of 2150 rad/s. a) What duty cycle is required to run the motor at 1311.5 rad/s?...
