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 is reduced 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 chips (high current can cause immediate failure) 2. Output over-current protection is active during normal operation. Due to high power and current levels, do not artificially short-circuit the module when malfunctioning. Short circuits may result in circuit or component damage. For initial wiring tests, use low voltage and low current first. Once confirmed safe, proceed with higher voltage and current. As this is a bare board 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 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 items not included Note: Lighting and display differences may cause slight color variations between image and actual item.
