Working voltage: 6-20V (limit 24V) Drive current: nominal 30A plus air cooling 50A Maximum power: 1000W Overcurrent protection: Yes Locked-rotor protection: Yes (after locked-rotor, the current will automatically drop and run at intervals) Overtemperature protection: Yes (overtemperature power is halved) Maximum speed: 224000 RPM (2-pole motor), 74000 RPM (6-pole motor), 40000 RPM (12-pole motor), 35000 RPM (14-pole motor). Precautions: 1. Switching the positive and negative poles of the power supply on the motherboard will cause permanent damage to some of the chips on the board (the power does not work for a few seconds) 2. There is sampling overcurrent protection at the motor output during normal operation. Since the power and current of the module are large, do not artificially short-circuit the module when the module is not working normally. When the short circuit occurs, the circuit may be burned 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 bare circuit board module, pay attention to the insulation of the wiring head. It is strictly forbidden to touch the circuit board parts 3. Do not connect the motor that is obviously inconsistent with the module voltage, current or power to avoid unexplained 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 The above package content only, other products are not included.
