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 (current automatically reduces and operates intermittently) Over-temperature protection: Yes (power reduces 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) Model Number: Motor Driver Board Precautions: 1. Reversing the positive and negative connections on the power supply may cause permanent damage to internal chips (failure may occur within seconds) 2. The motor output has sampling-based over-current protection during normal operation. Due to high power and current levels, do not artificially short-circuit the module when malfunctioning. Short circuits may result in burnt circuits or component failure. For initial wiring tests, use low current and low voltage first. Once confirmed safe, proceed with higher current and voltage. As this is a board module, ensure proper insulation of wiring connections. Do not touch internal board components. 3. Do not connect motors that significantly exceed the module's specified voltage, current, or power ratings to prevent unexpected damage Color: As Shown Material: PC+Plastic Package Contents: 2 x DC 6-24V 1000W BLDC 3-Phase Brushless Motor Driver (Due to different product batches, appearance may vary slightly, which does not affect functionality) Only the items listed above are included; other products are not included.
