Feature

DROK motor control board operation voltage range is DC 6-50V, highest power is 380W, rated current is 16A, MAX output current is 20A.
The motor speed controller is fit for DC brushless three-phase motors without Hall sensor.
PLC PWM Signal Control: the BLDC circuit is a new version, supports PLC 0-5V PWM signal control.
Speed Control Function: this brushless motor controller module is with controlling switch, convenient to regulate the motor speed.
Over Current Protection: the dc motor controller module is designed with over current protection, will be shut down the module and no output if over current.

Description

DROK BLDC Motor Controller

Parameters:
Operation voltage range: 6-50V
Rated current: 16A
Max output current: 20A
Max power: 380W
Over-current protective function: Yes
The highest rotating speed: 10000~15000 revolutions
Dimension: 63x45x30mm

Wiring Ports:
1. MA MB MC: phrase line output connects to the motor
2. 5V GND: mainboard built-in power supply (the current cannot be exceeded 30MA)
3. VCC GND: the motor power supply (connect to external DC power supply)
4. SC: output pulse signal of rotating speed
5. Forward and reverse control: forward and reverse rotation control (or can be connected to the external switch)
6. VR: speed control signal input (with an onboard potentiometer for speed regulation, can also be connected to external 0-5V analog simulation, PWM duty cycle, support dual signal input speed regulation)

Notes:
1. We recommend adding the fuses, as without fuses on the power supply circuit of the motherboard. The reversed connection will cause some of the chip permanent damage.
2. In the normal operation, the motor output has the over-current protection. Please do not artificially short-circuit, because the module power current is large. Once short-circuit, has the possibility of burning line tube. Please use low current low-voltage testing in the first wiring test; then connect the larger current and voltage. Due to the bare board module sold, please attention wiring thread insulation and prohibited strong voltage touch onboard parts.
3. Do not connect the drive motor which has obviously inconsistent voltage, current, power, to avoid the unreasonable damage.

Package Includes:
1 x DC Brushless Motor Driver Board
