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 (high current exposure for even a few seconds can result in failure) 2. The motor output has over-current sampling protection during normal operation. Due to high power and current levels, do not short-circuit the module when malfunctioning. A short circuit may cause circuit damage or component failure. For initial wiring tests, use low voltage and low current first. Once verified, proceed with high voltage and high current connections. As this is an exposed board module, ensure proper insulation at wire 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 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 listed item is included; other items are not part of the package.
