Working voltage: 6-20V (maximum 24V) Drive current: rated 30A with air cooling up to 50A Maximum power: 1000W Overcurrent protection: Yes Locked-rotor protection: Yes (automatically reduces current and operates 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) Model Number: Motor Driver Board Precautions: 1. Reversing the positive and negative connections on the power supply may cause permanent damage to internal components (failure may occur within seconds) 2. The output includes over-current protection during normal operation. Due to high power and current capacity, do not short-circuit the module when malfunctioning. Short circuits may result in circuit damage or component failure. For initial testing, use low voltage and low current. Once verified, proceed with higher voltage and current. 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 (appearance may vary by batch, does not affect functionality) Package includes only the items listed above; other items are not included Note: Lighting and display differences may cause slight color variations between the image and actual item.
