Brushless DC motor potentiometer module with metal housing, compact size, and direct speed control. Key benefits: - Direct speed control without external control signals, making setup simple and reliable. - Smooth, low-noise operation with reduced vibration, which lowers motor wear and maintenance. - High efficiency and high output torque, enabling stronger drive performance while keeping energy use lower. - Small metal form factor that fits into compact installations. Specifications: - Material: Metal. - Package: 1 piece. - Size: Approximately 45 x 26 x 12 mm, excluding wires and protruding capacitors. - Control: Built-in potentiometer for direct speed adjustment and external analog 0-5 V input compatibility for PLC or other controllers. How it works: - The standard potentiometer adjusts motor speed directly when connected to a compatible brushless driver board, with speed increasing when turned clockwise and decreasing when turned counterclockwise. - For external analog control, remove the potentiometer cable and connect the external 0-5 V control signal and ground to the input signal terminal on the brushless driver board; two wires are sufficient. Performance and advantages: - Three-phase brushless DC design delivers relatively large output torque, improving the capability of the driven equipment. - Efficient power conversion reduces energy loss and supports higher output without excessive heat. - Reduced mechanical wear compared to brushed drives results in longer service life and lower maintenance needs. - Built-in motor stall protection helps prevent excessive currents during normal operation. Installation and wiring guidance: - Ensure correct polarity when connecting the power supply to avoid irreversible damage to control board components. - For the first wiring test, use a low-voltage, low-current setup to confirm correct connections before applying full voltage and current. - Verify that the motor voltage, current, and power ratings match the drive module specifications before connecting the motor. Precautions: 1. The motherboard may not include a fuse in the power supply circuit; add an appropriate fuse if none is present to protect the board. 2. Reverse polarity of the power supply can cause permanent damage to onboard chips even with brief exposure, so double-check polarity before powering on. 3. Do not artificially short the module during troubleshooting, because high currents can burn wiring or damage components. 4. Do not connect a motor that clearly exceeds the voltage, current, or power capability of the drive module to avoid unexplained damage. Practical applications: - Small electric vehicles and scooters requiring compact, smooth speed control. - RC models, robotic platforms, or automation systems that use a brushless driver board and benefit from either manual potentiometer adjustment or 0-5 V analog control from a PLC. - Fans, pumps, or conveyor rollers in light industrial or laboratory setups where low noise, reduced vibration, and high torque are required. Additional notes: - Allow a manual measurement tolerance of 1 to 3 mm for the listed dimensions. - Actual item color may vary slightly from images due to monitor differences, so please refer to the received product for final appearance.
