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 (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 components (failure can occur within seconds) 2. The motor output has over-current protection during normal operation. Due to high power and current levels, do not short-circuit the module when it is malfunctioning. Short circuits may result in circuit burnout or component failure. For initial testing, use low voltage and low current. Once verified, proceed with higher voltage and current. As this is a board-type 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 (Note: Due to different production batches, appearance may vary slightly but does not affect functionality) Note: Light reflection and differences in display screens may cause slight color variations between the image and the actual item.
