Working voltage: 6-20V (limit 24V)<br> Drive current: rated 30A plus air cooling 50A<br> Maximum power: 1000W<br> Overcurrent protection: Yes<br> Locked- protection: Yes (after locked-, the current will automatically drop and run at intervals)<br> Over-temperature protection: Yes (over-temperature power is halved)<br> Maximum speed: 224000 RPM (2 pole motor), 74000 RPM (6 pole motor), 40000 RPM (12 pole motor), 35000 RPM (14 pole motor).<br> Precautions:<br> 1. Reverse connection of the positive and negative poles of the power supply on the motherboard will cause permanent damage to some of the chips on the board ( current will not work for a few seconds)<br> 2. There is sampling over-current protection at the output of the motor during normal operation. Because the power and current of the module are , do not artificially short-circuit the module when the module is not working normally. the short-circuit, the circuit may be burnt and the tube may , the first wiring test test with low current and low voltage. After ok, connect with high current and high voltage. Since it is a board module, pay attention to the insulation of the wiring head. It is strictly forbidden to touch the board parts<br> 3. Do not connect the motor that is obviously inconsistent with module voltage, current, or power, to avoid inexplicable damage<br> Model Number: Motor Driver Board<br> color:As shown<br> Material:Plastic + Metal<br> Package Contents:<br> 1 x DC 6-24V 1000W BLDC 3-Phase Brushless Motor Driver<br> Only the above package content, other products are not included.<br> Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
