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 components 2. The output includes over-current protection during normal operation. Due to high power and current, do not short-circuit the module when malfunctioning. Short circuits may cause component failure or damage. For initial testing, use low voltage and low current. Once confirmed functional, proceed with higher voltage and current. Ensure proper insulation of wiring connections. Avoid direct contact with board components 3. Do not connect motors that 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) Only the above items included; other accessories not included Note: Lighting and display settings may cause slight color differences between image and actual item.
