Speed regulation range: 0~100% full speed (infinitely variable speed)
Size: 86 x 56 x 34mm
Net weight: about 86g
Instructions for use:
Motor: Suitable for all DC motors within 12~40 (only adjustable motors, not for other purposes)
Power supply: DC 12~40V power supply
Speed regulating potentiometer: Rotate to adjust the motor speed, adjustable to stop or full speed, unplug the potentiometer and the motor rotates at full speed
PWM:
Pulse width modulation is a very effective technology that uses the digital output of a microprocessor to control analog circuits. It is widely used in many fields from measurement and communication to power control and conversion.
Principles and advantages of PWM speed
A Peak of wave and a trough are a cycle, the Peak of wave has voltage and the motor rotates, and the trough voltage is 0 to stop the rotation. The cycle time of this block is 0.5MHz second, and the conversion cycle is 0.5 trillion times per second. Traditional speed regulation adjusts the motor speed by changing the voltage, which has poor adjustability and low efficiency. PWM weekly system adjusts the conversion cycle time, vector adjustment efficiency is higher
