DC brush motor PWM speed DC motor motor pump control board

DC brush motor PWM speed DC motor motor pump control board

1. Introduction

LC-Motor-BDCM DC brush motor control board using LM339 chips and MOS tube design, by adjusting the external potentiometer for speed regulation, can be used to drive DC14V to 37V current is not more than 5 a of DC brush motor.

2. performance feature

-1: Power supply: DC14V to 37 v.
-2: Motor models: DC brush motor  (DC14 to 37 v, current < 5 a).
-3: External control potentiometer for speed regulation.
-4: Have over-current protection function, choose different sampling resistance, current flow valve is different.
-5: Using high power MOS burned fly-wheel diode effective protection.
-6: MOS tube and fly-wheel diode with a heat sink, convenient heat in time, prevent the MOS tube and fly-wheel diode burned.
