1. This driver is a low-power brushless driver, and can also be embedded in other systems 2. 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 cooling 3. This driver is a DC three-phase brushless Hall-free control board motor that can work normally without Hall 4. The board has a potentiometer speed control and supports PLC0-5V analog signal speed control 5. The single-core driver can replace brushless driver using DVR11873 chip on market, with good performance and multiple functions, and can stably drive almost all small motors and hard disk motors<br><br>Product name: three-phase brushless DC without Hall drive Working voltage: 6-20V (limit 5-24V) Drive current: rated 2A 3A Maximum 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 use.
