Community collaboration is a great thing. Take the Arduino PWM library for shift registers. Some folks at the Arduino forum pitched in and helped [Elco] trim off a bunch of clock cycles by using th… ...

The MOSFET then modulates the 24V-dc motor-supply rail and thus generates a more-than-95%-efficient, programmable motor-speed control. The motor's armature inductance combines with flyback diode D3 to ...

The company was early into adding phase-locked loop clock multipliers to give the PWM machinery something faster than the processor clock to work with. Arduino offers a simple framework to programme ...

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.

A PWM speed control, it promises cool motor operation, long brush life, low noise, and a wide speed range. For more info, call BODINE ELECTRIC CO., Chicago, IL. (800) 726-3463.

Direct torque control is a motor-control method for ac drives that accurately regulates motor speed and torque without encoder feedback from the motor shaft. Eliminating encoders can simplify ...

The claim is that it can reject PWM slew rates of >500V/µs and settles within 500ns to provide a 0.3% accurate (of full-scale) measurement of winding current “allowing motor control designers to ...

Makers, developers and Arduino enthusiasts searching for silent stepper drivers with high resolution encoders which are also Arduino compatible.
