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 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 levels, 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 open board design, ensure proper insulation of wiring connections. Do not touch internal board components. 3. Avoid connecting motors that significantly exceed the driver modules specified voltage, current, or power ratings to prevent damage.
