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?...

Need to figure out the coding to complete this Circuit
Board.
If you are able to post how the Circuit will be wired with the
Arduino and the Motor Controller as well that would be great.

Given a 1/4 hp, separately excited, dc motor with the following parameters: K = 0.61, R, 15Ω, La-120mb. J = 0.005, and b = 0.0006. The armature voltage is controlled by a 120-V dc PWM source operating at 100 Hz 1. What is the armature current if the no-load speed is 1800 rpm when the armature supply is operated at a 100% duty cycle? 2. What is the no-load...

Arduino 8 Sonic Sensor Motor Control Due: Jun 25, 2018 at 11:59 PM 1. Using a sonic sensor, display the distance to an object (e.g. wall, book, etc) in inches and feet 1. Using the above calculated distance, create a closed-loop (or feedback loop) controller to control the speed of a DC motor 1. For distances less than or equal to 1 ft (12") send the motor a PWM signal of 50 2. For distances...
