  • How do I know if my brushless motor is bad?

    Check for short circuits between the stator and the windings. Look for any connection between the windings and the motor stator laminations. You will need to find bare metal on the stator for one connection to the meter and on the meter windings for the other.

  • How to read BLDC motor specifications?

    RPM rating (speed) – high speed applications require a BLDC motor with higher RPM and the other way round. Usually, the speed will be indicated by the Kv and included in the specs sheet. A higher number means a higher level of RPM. To find a brushless DC motor highest speed, multiply the Kv rating by the voltage.

  • Can BLDC motor run without ESC?

    You can't even run a brushless DC motor without the ESC, let alone control it.

  • Why is there 3 wires on a brushless motor?

    These coils are energized in a particular order to create a series of electromagnetic forces that 'pull' the bell (which contains permanent magnets) around. As there are three sets of coils, there are three wires - one for each set of coils so they can be individually energized.

  • Can BLDC work without Hall sensor?

    Hall sensors are necessary if you want a BLDC to start with high torque, or be controlled down to very low speed. If you simply want a spinning motor for a propeller, then the ESC can work with the back EMFs from the coils themselves to control current and speed, after a few trial pulses have kicked it into motion.
