Rate etc. matches.Generally all it is first to set various parameters therefore because gas pressure in vacuum and discharge power are relatively easily adjusted,
Air pressure and discharge power are adjusted again until motor output power is maximum.
The quantity of sawtooth on stator and rotor can be with identical, can also be different.Due to the sawtooth on stator and rotor all
