DC 6.5-50V 380W BLDC 3 Phases Brushless Motor Controller Board No Hall Sensor PWM Driver Module for Fans/Robot

DC 6.5-50V 380W BLDC 3 Phases Brushless Motor Controller Board No Hall Sensor PWM Driver Module For Fans/Robot This drive is a DC three-phase brushless and Hallless control board, and the motor can work normally without Hall. BLDC wide voltage 6.5-50V high power 380W DC three-phase high-speed brushless sensorless controller, new PWM signal input support 3.3V system PLC 0-5V analog signal input control Special instructions for external signal input: 1. The connection of the V/P short contact means that the PWM signal input effectively recognizes the real PMW signal to support the 3.3V system, and the PMW signal needs to be input from the two ports (PWM GND) of the terminal. 2. When the V/P short contact is disconnected, the 0-5V analog signal input is valid (the default is disconnected at the factory). When the analog quantity is input, the on-board potentiometer can be used to adjust the speed. If you want to connect an external 0 For -5V analog signal input, you must unplug the jumper cap on the board to cut off the potentiometer divider signal, and then input the 0-5V analog signal from the two ports (0-5 GND) of the terminal. The maximum voltage should not exceed 5V 3. The forward and reverse rotation and the brake are grounded through a switch, which is low-level effective. The external MCU can also give low-level signals. The front row of wiring terminals are weak current signals directly input to the MCU main control, and cannot be touched or touched. High voltage and strong current. Interface Descriptions: 1.U V W 3-phase line output connected to brushless motor 2. 5V GND The motherboard comes with 5V (current does not exceed 200MA) 3. VCC GND main power supply (external DC power supply) 4. SC speed pulse signal output (only the interface is reserved, no technical support) 5. DIR forward and reverse control keep low level effective (can be connected to the ground external switch)
