Composite materials in the rotor for a unique light weight electric motor for electric aircraft

Purpose and goal: Aim:

a) Find a cheap, mass-producible and more lightweight solution for the design of the rotor for Hagnesia´s electric motors, to make them even more attractive for electric aircraft.

b) Hagnesia shall learn more about the possibilities of composite materials and establish a good contact with Compraser labs (Rise). För Hagnesia has great value in finding good technical solutions, and expanding our network. Objective:

a) Find a production-friendly design solution to build the rotor´s structural material partly from composite materials. b) Manufacture a test section of such a rotor. Expected results and effects:

a) Hagnesia finds better solutions for how the rotor should be designed and manufactured for this type of electric motor. The solution will most likely include a composite solution for the structural material of the rotor. b) Hagnesia develops the relationship with Rise Compriser Labs for future collaborations.

c) Hagnesia builds and tests a test section of a rotor with a new design solution. d) This project will be a springboard to future projects in electric aviation. Approach and implementation: WP1: Feasibility study and design with workshops. 2024-07-01 - 2024-11-05

Various design proposals are produced, and an evaluation including workshops takes place where the best candidate for test manufacturing is selected. A mapping of motor specifications for different aircraft models is also carried out. WP2: Production of test segment and evaluation. 2024-11-06 - 2024-12-31

A test segment is built in Hagnesia´s premises and evaluated, with support from Compriser Labs. The lessons learned from the project are documented and ideas for further projects are developed.
