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. Output over-current protection is active during normal operation. Due to high power and current, do not short-circuit the module when malfunctioning. Short circuits may result in component failure or damage. For initial testing, use low voltage and low current. Once confirmed functional, proceed with higher voltage and current. As this is an open board design, ensure proper insulation of wiring connections. Do not touch internal board components 3. Avoid connecting motors that significantly exceed the module's specified voltage, current, or power ratings to prevent 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 image and actual item.
