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