Working voltage: 6-20V (limit 24V) Drive current: rated 30A with air cooling up to 50A Maximum power: 1000W Overcurrent protection: Yes Locked-rotor protection: Yes (after locked-rotor, current will automatically reduce and operate intermittently) Over-temperature protection: Yes (power is reduced by half when overheated) Maximum speed: 224000 RPM (2 pole motor), 74000 RPM (6 pole motor), 40000 RPM (12 pole motor), 35000 RPM (14 pole motor). Precautions: 1. Reversing the positive and negative terminals of the power supply on the motherboard may cause permanent damage to some chips (high current can cause failure within seconds) 2. Output over-current protection is active during normal operation. Due to the high power and current of the module, do not artificially short-circuit the module when it is not functioning properly. A short circuit may result in circuit burnout or component failure. For initial wiring tests, use low current and low voltage. Once confirmed safe, proceed with high current and high voltage connections. As this is an exposed board module, ensure proper insulation at wire connections. Do not touch board components. 3. Do not connect motors that significantly exceed the module's specified voltage, current, or power ratings to prevent unexpected 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 products are not included.
