What kind of electronics are inside of Thruster motor?

There are some beeps when we turn on the motor. What kind of electronics are inside. ? I dont see any reference about. If it stay powered in neutral about 20 minutes the beeps starts in 1 Hz.

Hi @acjacques,

There are no electronics at all inside the thrusters besides the BLDC motor itself. The beeps are coming from the motor, but they are actually generated by the ESC, its using the motor as a speaker.


Ok. Now make sense.

What kind of thruster should I buy

Hi @leaf,

If you’re using our Basic ESC:
