Why Cutting Brushless Motor Wires can Destroy your Motor (Or even ESC)

You may want to cut your brushless motor wires back to either save some wiring room or just to benefit from the performance gain. Either way, before you do so, you must know if its safe.

In fact, cutting the wires on your brushless motor could turn your motor in to a paper weight if you can't undo the damage.

Many brushless motor have the winding termination actually completed outside of the motor. If you were to cut the wires, you would effectively remove this termination point. Should this go unrealized, the next time you run power to the motor, you can ultimately destroy the ESC through short circuits created in the winding.

However, if the termination of the windings is performed inside the motor, then cutting the motor wires is safe.

To ensure you may be able to cut the motor wires located on your motor, it is recommended that you contact the manufacturer.
