Precautions: 1. There is no fuse in the power supply circuit on the motherboard. has added it himself. Reverse connection of the and negative poles of the power supply will cause permanent damage to some of the on the board (even if it does not work for 1 second). 2. There is motor blocking protection during normal operation. do not artificially short-circuit when the module is not working normally. Once short-circuiting may cause to burst, use small current and low voltage test for the first wiring test. Matching use of three-phase DC brushless motors with equivalent current and power. 3. Do not connect the motor that is obviously inconsistent with module voltage, current, or power, to avoid inexplicable "nonsensical" damage. Features: This driver is a low-power fan brushless driver, and it can also be embedded in other . It is specially used for air pumps, water pumps, oil pumps, fans, etc. and industrial control electric gadgets for small space and low-power DC three-phase brushless motors. Default The middle timing is not suitable for high-power motors, such as long-term full load current operation, plus fan cooling. Interface Description: 1. U V W phase line output is connected to the motor 2.
