This driver adopts square wave control (also called trapezoidal wave control, 6-step commutation control), which can drive It can control brushless motor with sense (with Hall sensor) and without sense (without Hall sensor). It can drive and control the brushless motor with sense (with Hall sensor) and without sense (without Hall sensor), accurately detect the current and speed, and carry out the closed-loop control of speed loop and open-loop control to realize the motor acceleration and deceleration and steady speed control. The inductive drive control adopts the four-quadrant control , which can generate the force opposite to the direction of rotation, so that the descending slope or lifting heavy objects will not stall; the non-inductive drive is the two-quadrant control .Support internal potentiometer, external potentiometer, 0-10V analog voltage, PWM, 485 communication, model airplane Remote control, remote lever and other control methods, support speed closed-loop and open-loop two operating modes. Support acceleration and deceleration control, slow start and slow stop effect can be set Colour:As Shown Material:PCB Package Contents: 1 x Brushless Motor Drive Board Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
