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 after lock) 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) Precautions: 1. Reversing the positive and negative connections on the motherboard 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 result in circuit damage or component failure. For initial testing, use low voltage and low current. Once verified, proceed with higher voltage and current. As this is an exposed board module, ensure proper insulation of wiring connections. Avoid touching internal 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 Note: Lighting and display differences may cause slight color variations between the image and actual item.
