Producte acabatview
The RioRand DC Brushless Motor Speed Controller is designed for efficient and reliable control of three-phase brushless motors, including those without Hall sensors. Its wide voltage range and high power capability make it suitable for various applications.

Característiques clau
- DC three-phase brushless Hall-free control board, compatible with motors without Hall sensors.
- Ampli voltage input: 5-50V.
- High power output: 300W.
- Speed control supports three signal inputs: PWM signal, PLC 0-5V analog voltage, and 1-4.2V Hall handle input.
- Motor output for sampling overcurrent protection.
2. Configuració
Esquema de cablejat
Carefully follow the wiring diagrams below to connect the motor speed controller. Ensure all connections are secure and correct to prevent damage.



Configuració Inicial
The board features a speed regulating potentiometer. In PWM input or external potentiometer control modes, this potentiometer needs to be adjusted to the minimum setting (fully counter-clockwise) to allow external control.

3. Instruccions de funcionament
Control de velocitat
The controller supports multiple methods for speed regulation:
- On-board Potentiometer: Adjust the blue potentiometer on the board to control motor speed. Clockwise increases speed, counter-clockwise decreases speed.
- Entrada de senyal PWM: Connect an external PWM signal to the designated input. The board will respond to the duty cycle of the PWM signal.
- PLC 0-5V Analog Input: Use a PLC or similar device to provide a 0-5V analog voltage signal for speed control.
- 1-4.2V Hall Handle Input: For applications requiring a Hall handle, connect it to the specified input.
Ensure the correct input mode is selected via the switch button on the board (refer to Figure 5 for details).

4. Manteniment
To ensure the longevity and optimal performance of your RioRand motor speed controller, observe the following maintenance guidelines:
- Polaritat de la font d'alimentació: Always ensure the power supply positive and negative poles are connected correctly. Reversing polarity will cause permanent damage to the board.
- Eviteu curtcircuits: Due to the high current capabilities, do not intentionally cause a short circuit during normal operation, as this will damage internal components.
- Wiring Insulation: As this is a bare board module, pay close attention to wire insulation when wiring to prevent accidental contact and short circuits. Avoid strong voltage contact with the board.
- Compatibilitat del motor: Do not connect motors with incompatible voltage, current, or power phase specifications to avoid damage.
- Neteja: Keep the board clean and free from dust and debris to prevent overheating and malfunction.
5. Solució De Problemes
If you encounter issues with your motor speed controller, consider the following:
- Motor Not Starting or Irregular Operation: Verify all wiring connections are secure and correctly matched according to the diagrams. Check that the input signal (PWM, analog, Hall handle) is within the specified range and the correct input mode is selected.
- Overcurrent Protection Triggered: If the motor output experiences a short circuit or excessive load, the overcurrent protection may activate. Reduce the load or check for short circuits in the motor wiring.
- Sense alimentació/indicador lluminós apagat: Comproveu la font d'alimentació voltage and ensure it is within the 5-50V range. Confirm that the power supply polarity is correct.
For any unclear wiring or usage concerns, or if problems persist, please contact customer support for assistance.
