Evaluation of the operation of the fan of the combine harvester air-and-screen cleaning system when using an asynchronous electric motor as a drive

Abstract

The article presents the results of a study of a combine harvester fan after making design changes aimed at facilitating air flow control in airand-screen cleaning. To this effect, the mechanical drive of the combine harvester fan was replaced with an electric one having an automated control system based on variable-frequency drive (VFD).
