Motherboard specifications:
Working voltage: 6-20V (limit 24V)
Drive current: rated 30A plus air cooling 50A
Maximum power: 1000W
Overcurrent protection: Yes
Locked-rotor protection: Yes (after locked-rotor, the current will automatically drop and run at intervals)
Over-temperature protection: Yes (over-temperature power is halved)
Maximum speed: 224000 RPM (2 pole motor), 74000 RPM (6 pole motor), 40000 RPM (12 pole motor), 35000 RPM (14 pole motor).
Precautions:
Reverse connection of the positive and negative poles of the power supply on the motherboard will cause permanent damage to some of the chips on the board (large current will not work for a few seconds)
There is sampling over-current protection at the output of the motor during normal operation. Because the power and current of the module are very large, please do not artificially short-circuit the module when the module is not working normally. Once the short-circuit, the circuit may be burnt and the tube may burst, the first wiring test machine Please use small current and low voltage test, after ok, then apply high current and high voltage. Because it is a bare board module, please pay attention to the insulation of the wiring head. It is strictly forbidden that strong voltage touches the board parts.
Do not connect the motor that is obviously inconsistent with the drive module voltage, current, or power, to avoid inexplicable damage
