produced) 2) Relatively cheap 3) Makes the motor run better The disadvantages of PWM systems: 1) PWM circuits are complicated 2) Sensitive to electromagnetics and could interfere with radio signals, cause vibration frequencies, which causes noise. The frequency should be about 30kHz, voltage 5V.
2. Recommend the suitable range of frequency for this PWM applied in microcontrollers. Analyze the advantages and disadvantages of PWM systems. The frequency should be about 30kHz, voltage 5V. The advantages of PWM systems: 1) Very high efficiency (not much heat produced) 2) Relatively cheap 3) Makes the motor run better The disadvantages of PWM systems: 1) PWM circuits are complicated 2) Sensitive to electromagnetics and could interfere with radio signals, cause vibration frequencies, which causes noise.
during the operation with a constant PWM signal of 50% duty cycle. 2. Recommend the suitable range of frequency for this PWM applied in microcontrollers. Analyze the advantages and disadvantages of PWM systems. The frequency should be about 30kHz, voltage 5V. The advantages of PWM systems: Very high efficiency (not much heat produced) Relatively cheap Makes the motor run smoother The disadvantages of PWM systems: PWM circuits are complicated Sensitive to electromagnetics and could interfere with radio signals, cause vibration frequencies, which cause noises.
