ABYA 380W 3 Phases Brushless Motor Controller Board(No/Without Hall Sensor) BLDC PWM PLC Driver Board DC 65-50V Interface Description:MA MB phase line output motor;5V GND motherboard with its own power supply (current does not exceed 30 mA); GND main motor power supply (external DC power supply);SC speed pulse signal output;Control interface forward and backward (can also drive external switch);VR speed signal input (the integrated potentiometer speed control can also be connected to the external 0-5V speed control;brake_x000D_ Overheat protection: Yes (more than 100, half the power is reduced)_x000D_ Maximum speed: 224000 RPM (2-pole motor), 74000 RPM (6-pole motor), 40000 RPM (12-pole motor), 35000 RPM (14-pole motor)_x000D_ Motherboard specifications:_x000D_ Product Name: 380W Brushless DC Motor Driver_x000D_ Operating voltage: 6.5-50V_x000D_ Maximum current: Nominal from 16 to 20A_x000D_ Maximum power: 380 W_x000D_ Overcurrent protection: no (external fuse required)_x000D_ Blocking protection: Yes (the current be lowered automatically after blocking)_x000D_ Colour:yellow_x000D_ Material:plastic_x000D_ Size:length 63 MM * width 45 MM * height 30 MM_x000D_ Package Contents:_x000D_ 1*Motor controller board_x000D_ Precautions:_x000D_ 1. The power circuit of the main board has no fuse, and the built-in self-addition cause the board chip to be permanently damaged (even if it is 2 seconds)._x000D_ 2. During normal operation, there is a sampling overcurrent protection at the motor output. Since the power and current of the module are very large, do not short circuit when the module does not work normally. Once the short circuit has the possibility of burning , the first wiring test machine uses low current and low voltage, after ok, high current and high voltage passes, because it is a bare board module for sale , pay attention to the wiring line insulation, strong voltage is not allowed to touch the board parts._x000D_ 3. Do not connect the motor that is clearly inconsistent with the vol and current of module or that is far from each other._x000D_ _x000D_ Only the above package content, other products are not included._x000D_ Note: Light 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. _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_
