ITEM NAME:380W 3 Phases Brushless Motor Controller Board(No/Without Hall Sensor) BLDC N3D7 380W 3 Phases Brushless Motor Controller Board(No/Without Hall Sensor) BLDC N3D7 Interface Description:MA MB MC phase line output motor;5V GND motherboard with its own power supply (current does not exceed 30 mA);VDC 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 Overheat protection: Yes (more than 100, half the power is reduced) Maximum speed: 224000 RPM (2-pole motor), 74000 RPM (6-pole motor), 40000 RPM (12-pole motor), 35000 RPM (14-pole motor) Motherboard specifications: Product Name: 380W Brushless DC Motor Driver Operating voltage: 6.5-50V Maximum current: Nominal peak from 16 to 20A Maximum power: 380 W Overcurrent protection: no (external fuse required) Blocking protection: Yes (the current will be lowered automatically after blocking) Colour:yellow Material:plastic Size:length 63 MM * width 45 MM * height 30 MM Package Contents: 1*Motor controller board Precautions: 1. The power circuit of the main board has no fuse, and the built-in self-addition will cause the board chip to be permanently damaged (even if it is 2 seconds). 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 line, 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. 3. Do not connect the motor that is clearly inconsistent with the vol
