    Tips: Brushless DC motor controller troubleshooting

    The motor does not rotate.

    • Insufficient voltage. Test whether the voltage of the third pin of the MCU exceeds 3.2V.
    • Whether the brake level connection method is normal, check pin 7 of the MCU, the voltage of the high-level brake exceeds 2.5V, and the voltage of the low-level brake exceeds 2.0V.
    • Whether the speed regulating voltage is added to the 5th pin of the MCU.
    • The connector is improperly installed, and the output cannot be output due to lack of phase.
    • When the above conditions are met, the output and drive circuit malfunctions, the external force forces the motor to rotate, and there is obvious uneven resistance inside, the MOS power tube is damaged, but some of the front-end drive transistors are damaged..

    The motor rotates, but abnormal.

    • Check whether the controller's working mode of 60 degrees and 120 degrees corresponds to it.
    • The motor is the ability of external force, there is a loud operating sound when rotating, and the output is not stable. Check the condition of the connection line. The components of the circuit board have missing welding, virtual welding, short circuit, wrong welding, etc.
    • Hall signal error, some motors need to adjust the output line and Hall signal line of the controller
    • The motor is unstable when rotating at low speed, and the parameters of the drive circuit components are too different. Test whether the three-phase drive components are welded incorrectly, and the performance is different.

    The motor is easy to stop and the load capacity is poor.

    • Whether the controller short-circuit comparison resistance R9, R10 is 20K or 1.2K.
    • Capacitor C7 (1000Pf), dead zone adjustment capacitor C24 (100PF) capacity deviation is too large
    • Constantan wire is too long (When the capacity of the controller capacitor C7, C24 is wrong, the working current is abnormal, the general working current is large, and the constantan is too long)
    • Some parts of the drive circuit are leaking and have poor performance.

    The current-limiting resistor is heated, and the static current is too large.

    • There is a short circuit in the detection circuit.
    • Whether the driver output has a component welding error.
    • Whether the connection in the plug-in corresponds.

    Flammable MOS tube or motor runs normally at low speed, and when the handle rises quickly, the flammable MOS tube.

    • Check whether the HC27 circuit (U3) normal.
    • The voltage of pin 21 of the single-chip microcomputer is not the high level or low level of the logic check, and its pull-up resistance is open or soldered.
    • The MOS drive signal cannot normally follow the output signal of the single-chip microcomputer, showing a normal level, and it is most likely to damage the MOS.

    After adding the signal, the signal light goes out, but the motor does not rotate.

    • Whether the motor output is well connected.
    • The motor hall is not connected.
    • The drive circuit has equipment open circuit or false soldering, missing soldering, etc.

    Wonderful brushless dc motor controller
    This brushless dc motor controller works great. Did exactly what I wanted it to do. Works as described. Easy to wire up. I think everything is perfect. I highly recommend this motor controller if you need one.

    Great brushless DC motor controller.
    I used this BLDC motor controller to run a 1.5 kW brushless motor to work with feedback. I’ve gone through several other BLDC controllers and this one is the best at its price point. Great product and I will recommend this controller to others.

    Is this a documentation error?
    All documentation says the Vcc going to the motor from pin 6 on the ATO-BLD-100A is either 5 V or 6.25 V. when measured, it is running at a nominal 12V, is this a documentation error?

    ATO Responded
    This is normal, the Hall voltage will actually be higher, which can better anti-interference.
