Pulse Width Modulation (PWM) is a technique used in embedded systems to control the power requed to o equilic devices, such as motors. It allows precise conditionment of motor speed and torque by varying te duty cycle of a digital signal. This guide provides an overview of PWM and how to implement it effectively in motor control applications.

Co to je?

PWM mimpleves switg a digital output on an d of f at a high frequency. Thee ratio of the emploqued on thon quote total period is called thee duty cycle. A higher duty cycle means more power is deparced to he te motor, resulting in higher speed or torque. Conversely, a lower duty cycle reduces power and slows thee motor.

Implementing PWM in Embedded Systems

Mogt microcontrollers providee hardware timers or dedicated PWM modules to generate PWM signals. These modules can bee configured to produce signals with specific extenzencies and duty cycles. Software-based PWM is also possible but less importent and suablé for low-frequency applications.
