Features Humanized design, the interface uses a terminal, a standard heat sink, and an integrated speed potentiometer on the board Full chip technology, stable performance, with forward and reverse, brake function, motor speed controller adopts Hall brushless controller Wide voltage 6‑60V high power 400W DC three‑phase brushless with Hall controller Support PLC 0‑5V analog control, support PWM to 0‑5V control, can be used when power is on, saving time and effort There are three relatively thick phase wires on the machine, and there are also three phase wire interfaces on the drive board, which are marked MA, MB, MC, etc. Specification: Item Type: Motor Controller Material: PCB Working Voltage: 6-60V Maximum Current: Rated 16A Maximum 20A Maximum Power: 400W Overcurrent Protection: Yes Package List: 1 x Motor Controller 1 x Terminal Line Note: 1. This drive is a DC three‑phase brushless control board, which requires the motor to have a Hall to work normally2. This drive is only suitable for DC brushless and Hall motors with an electrical angle of 120°3. When the PWM signal is input from the 2 ports of the motherboard P G , the amplitude is 2.5‑5V, and the frequency is 50HZ‑20KHZ.4. When the external analog 0‑5V input, input from the 2 terminal ports of the main board. 5. When the external potentiometer is used to adjust the speed, connect it to the 3 terminal ports of the main board (the potentiometer on the board is adjusted to the minimum, and the wiring is indicated by the potentiometer on the picture)6. The forward and reverse rotation and stop are grounded through a switch (0 potential). The low level is valid, and the external MCU can also give a low level signal. The brake is connected to a 5V high‑level effective through a switch. The front row of wiring terminals are all weak current signals directly input to the MCU main control, and cannot be touched or touched with high voltage and strong current.7. When the PWM signal is input from the 2 ports of the motherboard PG (the built‑in potentiometer on the board is adjusted to the minimum, and the short interface on the board is short‑circuited at the same time as shown in the figure above), the amplitude is 2.5‑5V, and the frequency is 50HZ‑20KHZ.8. When the external analog 0‑5V input, input from the 2 terminal ports of the main board (the potentiometer on the board is adjusted to the minimum, the wiring is shown by the dotted line in the figure above) Package List 1 x Motor Controller 1 x Terminal Line
