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 4. The board has a potentiometer speed control and supports PLC0-5V analog signal speed control 3. This driver is a DC three-phase brushless Hall-free control board motor that can work normally without Hall 5. 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 motors, Weight: 0.01984160358 pounds, Manufacturer: Gosera
