Pulse Widtr Modulation (PWM) is sebuah teknis uuse to controll te powir devied to electric devices, sHAN as motors.

Understanding PWM and Ducky Cycle

PWM acplives switching a signul on ol ol off f f high expantentenency.

Calculating Ducky Cycle for Motor Speedy

To kalkulate the duty cycle needed for sebuah spesifik motor speeded, consider the supply voltale and te motor 's characterstics. Te general formula is:

Sl1; Sl1; FLT: 0 AF3; Cycle Belanda (%) = (Desired Voltale / Supply Voltape) × 100 1f 1f FLT: 1 MIS3;;;

Pemeriksaan for, if the supply voltape is 12V and the desired mootor voltale for a certaizn speed is 6V, the duty cycle showd be:

FLT: 0 = 0 = 33; Cycle Belanda = (6V / 12V) × 100 = 50% 1; FLT: 1; Alpha3; Alpha33;

Implementing PWM in Microcontrollers

Ensure thate PWM expetency is apastenate for modor controlt to exvent noise inefilicieny. Typikal expeencies range frome 1 kHz to 20 kHz.

Summary of Key Points

  • Dully cycle detere the average powir supplied to te motor.
  • Kalkulate duty cycle using that e ratio of dededered voltale po supply voltale.
  • Konfigure microcontroller PWM registers with the kalkulated duty cycle value.
  • Use acuate PWM expetency for smooth modor operation.
