Dc Motor Whine at Donna Bradshaw blog

Dc Motor Whine. Popping capacitors across a brushed motor reduces noise from the motor, but to a fast pwm edge, those lovely capacitors. But, when i reduce the value to 50 or below, the whine. I also have a pot connected through which i can vary the speed. When you change the speed of a dc motor to less then the max speed they seem to make a high pitch whining noise. As expected, when the analogwrite function is used with a value of 255, the motor spins at full speed (no whine sound). Dc motors are still used because they offer exceptional speed and torque control. They prefer to zip and zag. Yet, you should never overlook the noise problems that surround dc. I have a dc motor connected to the arduino motor shield v3. High current spikes will occur as the capacitor charges, putting stress on the bridge transistors and increasing electrical noise in. Brushed dc motors aren't known for their ability to work well at slower speeds;

Why is my DC motor whining at a lower PWM frequency? Progressive
