San Diego, Calif.—ROHM Electronics has introduced an H-bridge driver IC line, offering designers a simple upgrade path to pulse-width modulation (PWM) speed control using either analog or digital ...

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 ...

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 ...

BHPian Chhanda Das recently shared this with other enthusiasts:Earlier this year, after an unfortunate incident of tea ...

This is a very cool electronic project to control dc loads using a very cheap and reliable design. This video also explains in depth all about pwm so you can understand it easily. #JoyplanesRC #pcb #J ...

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.

In use, the pot is adjusted until little speed variation occurs when the motor is loaded. Motor speed will start to oscillate (or run away) if over-compensation is applied, so back the control off a ...

Fan speed control Due to the high tolerances, when using thedirect PWM method the speed of fans has to be controlled. Maintainingthe nominal speed of the fan can be done through open loop and ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317.
