Usage Tips:1. This driver is a low-power brushless driver, and can also be embedded in other systems2. It is specially used for air pumps, water pumps, oil pumps, fans, etc. of small-space and low-power DC three-phase brushless motors and industrial control electric tools, etc. The default timing angle is medium and it is not suitable for high-power motors. If it works at full load current for a long time, it is recommended to add fan cooling3. This driver is a DC three-phase brushless Hall-free control board motor that can work normally without Hall4. The board has a potentiometer speed control and supports PLC0-5V analog signal speed control5. The single-core driver can replace the brushless driver using DVR11873 chip on the market, with good performance and multiple functions, and can stably drive almost all small motors and hard disk motorsProduct name: three-phase brushless DC without Hall driveWorking voltage: 6-20V (limit 5-24V)Drive current: rated 2A 3AMaximum speed: 22400RPM (2-pole motor), 74000RPM (6-pole motor), 40000 RPM (12-pole motor), 35000RPM (14-pole motor)Due to different batches, there may be differences in product appearance, color, and printed text, which not affect the use.Color: GreenMaterial: PCBPackage Contents:1 * Brushless Motor Driver Board KitOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
