This lets them be used in applications needing dynamic behavior and fast responses from the motor. Using PWM allows precise current control in the windings.

An all-in-one online tool from STMicroelectronics is designed to simplify motor-control designs using STM32 and STM8 microcontrollers (MCUs).

Although the principles of PWM drives are not new, advances in power semiconductors, control electronics, and microprocessors have increased their popularity.

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 this video, [Jack] talks about various types of pulse width modulation (PWM). You can use PWM to control the speed of a motor, the brightness of a LED, or to generate analog waveforms.
