Development and optimization of an electric machine for the harvesting of fourth-range leaf vegetables (CUP B43D18000330007)
About the project
M.IN.E.R.V.4 project

The aim of the project is the feasibility study on the design for the pre- industrial development of electromechanical components to optimize the full- electric operation of the harvesting machine. A study is proposed to fine-tune and resolve the design issues concerning the current model.

In particular, it is proposed to evaluate:  

  • the abolition of the mechanical gear system that trigger two types of machine gear (collected mode and return mode from the workplace), compensating with the adoption of an advanced electronic control system of wheel speed;
  • power factor analysis/energy absorption/costs concerning the use of traction system with motors with AC operating technology (alternating current) instead of current DC motors;
  • resizing the battery pack in relation to the optimization in terms of energy expenditure deriving from the development of the previous points and possible migration to better technology (optimization volume, weight and capacity of the battery pack).

Objectives

The project meets a pressing need for the development of short and medium term solutions regarding the sustainability of work machines and on the basis of a growing inseveration of European and international regulations on CO2 emissions.

In particular, from a first analysis, as criticality of the current project, the following have been identified:

  • the problem of the two types of gear (collection mode and return mode from the greenhouses) to be inserted with a mechanical type system;
  • advantages / disadvantages of the use of DC type traction motors and consequently we want to evaluate the feasibility of replacing them with AC motor type in order to achieve, as primary objective, better efficiency in terms of energy efficiency and performance;
  • need to optimize the volume and weight of the battery pack as currently it is very heavy, economically unsustainable and difficult to intervene in the event of maintenance and replacement.

Project implementation procedures

It is planned to address the feasibility study focusing on the following objectives:

 

  • the abolition of the mechanical gear system for the two types of gear and the adoption of an advanced electronic wheel speed control system;
  • the possibility of using AC motor wheels instead of the current ones in DC technology, the motive power-absorption analysis and the cost-energy optimization;
  • the resizing of the battery pack in relation to the optimization in terms of energy expenditure deriving from the development of the previous points and possible migration to better technology.

The results and updates will be presented on this site.
