Shorted windings

SpletWhat is a shorted winding? A short is a common winding breakdown, and it requires rewinding or replacing the motor. Shorted turns are caused by nicked coil wire, high … Splet06. jun. 2024 · Motor stuttering. The first thing you should check, is whether or not the motor screws are touching the windings, and make sure the motor wires are all connected to the ESC correctly and that all the solder joints are good. See my tutorial about how to solder. If that’s not the issue, then it could be bad MOSFET.

This phenomenon is known as field excitation. ... Electrical imbalances like open or shorted windings or unequal air gaps can produce noises or vibrations in addition to mechanical issues or imbalances ... SpletIt can detect a short circuit in the winding. It tests based on the loss in the inductor or transformer. Even a small number of short turns (and even a single shorted turns) will cause a significant increase in losses (a significant reduction in the Q factor).
