The speed control of the four-wheeler controller is the PWM (pulse width modulation) signal.
Because the four-wheeler controller regulates the speed of the motor by controlling the PWM signal of the motor, thus controlling the speed of the vehicle.
PWM signal is a periodic digital signal, by adjusting the duty cycle of the signal to change the time of the effective level of the signal and the time proportion of the invalid level, so as to control the average power output of the motor, and then control the speed of the vehicle.
At the same time, PWM signal can achieve acceleration, deceleration, braking and other functions by changing the frequency and duty cycle, which is a common control method in modern electronic systems. In addition to the four-wheeler controller, PWM signal is also widely used in brushless DC motor control, light regulation, audio coding, power management, temperature control and other fields, in industrial automation, energy management, communication technology, home appliances and other fields have a wide range of applications.
The four-wheeler controller controls the speed of the PWM line.
Because PWM(pulse width modulation) technology can adjust the output voltage by changing the proportion of the high and low level duration, so as to achieve the control of the motor, therefore, in the electronic control system of the four-wheeler, the controller uses PWM signals to control the speed of the motor. In addition, the four-wheeler controller can also dynamically adjust the speed and realize the braking function by receiving the signal of the speed sensor and the brake switch, thus ensuring the safety and stability of the driving. PWM technology is not only widely used in the electronic control system of four-wheelers, but also widely used in LED lighting control, wireless communication and audio coding and other fields, becoming a commonly used adjustment technology in modern electronic technology.
1 The four-wheeler controller controls the speed of the PWM (pulse width modulation) line.
2 By adjusting the width and frequency of the PWM line, the speed of the DC motor can be controlled, thus controlling the speed of the four-wheeler.
3 PWM line is a digital signal line, usually controlled by a microcontroller and driver chip, with accurate and reliable control effect.
