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.

All motor-control methods rely on a PWM voltage waveform to control the motor. The difference between control methods lies in how they calculate the motor’s voltage needs at any given moment.

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.
