It’s an excellent way to learn about both PWM motor control and the use of 555 timers, all with a very low parts cost and readily available components.

For receiving PWM indications, motor driver’s IC is connected to the micro-controller for distributing much wanted output for pace control of a small DC machine. In addition the DC motor speed control ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable ...

He hooks up the SN754410 to two motors, giving him speed and direction control for both based on the duty cycle of a PWM signal entering the chip for less than $2.50.

If you've got an Arduino of any variety, you might have noticed some of the pins on the board have a tilde mark or PWM printed next to them. What is PWM?

As a result of the efforts of Smart Motor Devices engineers, a cost-effective, full-featured and reliable controller BMD-20DIN ver.2 for DC brush motors is available now at the industrial market.

This DC servo motor controller can also be used with an external potentiometer or the integrated on board potentiometer. For applications with existing PWM signals available this can also be used ...

That’s basically everything except speed control of the motors. There are so many ways to control the speed of DC motors, but an easy way is to use pulse-width modulation. Here, applying a PWM signal ...

In designing a simple spectroscopy setup, we needed to synchronize the speed of a small, inexpensive dc motor precisely to 6000 rpm (100 Hz). Our first idea was to take a phase-frequency detector ...
