The working principle of the speed board is mainly based on the motor control theory and power electronics technology. 5437-1067A Its core purpose is to adjust the speed of the motor by changing the input voltage, current or frequency of the motor. The following is the working principle of some 5437-1067A common types of speed boards:

Dc speed board:
Voltage control: By changing the input voltage of the DC motor to adjust its speed. This method is simple and direct, but the speed range is limited.

PWM (pulse width modulation) control: Use a microprocessor to generate a PWM signal that adjusts the average voltage by changing the time ratio between high and low levels, thereby controlling the speed of the motor.

Current control: By detecting the current of the motor and feeding it back into the control circuit, closed-loop control is formed to ensure that the motor is operating at the desired speed.
Ac speed board (such as frequency converter) :

Frequency control: Adjust the speed of the motor by changing the frequency of power supplied to the AC motor. Inverter can convert fixed frequency alternating current into variable frequency alternating current.

Voltage control: Similar to DC motors, the speed of AC motors is adjusted by changing the input voltage.
Vector control: This is a more advanced control method that can independently control the magnetic flux and torque of the motor for more efficient and precise speed control.

Brushless Direct current Motor (BLDC) speed board:

Electronic commutator: Brushless DC motors use electronic commutators instead of traditional mechanical commutators. The speed regulating board changes the direction of the current by controlling the on-off of the electronic switch, so as to realize the positive and negative rotation of the motor.
PWM control: The same PWM technology is used to control the average input voltage of the motor, thereby adjusting its speed.

Intelligent speed board:

Microprocessor control: The use of microprocessor (such as DSP or ARM) to achieve more complex control algorithms, such as PID control, fuzzy control, etc., to improve the precision and response speed of speed regulation.

Sensor feedback: Integrated sensors (such as hall sensors, photoelectric encoders, etc.) to detect the actual speed and position of the motor, forming a closed-loop control system to improve the stability and accuracy of speed regulation.

The working principle of the speed board also involves power electronic components, such as MOSFETs, IGBTs, etc., which are used to achieve fast and efficient power conversion and control. Finally, the speed regulating board can accurately adjust the running speed of the motor by precisely controlling the input power of the motor.
