— a device that provides a stable puncture force regardless of the engine speed. A feature of the mechanics of electric motors is that without special adjustment, the puncture force decreases markedly with an increase in speed. This function allows you to maintain approximately the same level over the entire speed range, which has a positive effect on the quality of work.| puncture force | clear | Save List |
