Opti-feel

Objective

Precise assembly of the components of an electric motor is essential in order to meet the constantly increasing demands on torque and speed. Optical measurement technology is used to examine whether the required measurement tolerances can be achieved for the assembly of the next generation of motors.

In the Opti-Feel project, various measurement concepts are being investigated with the aim of demonstrating them on a real engine.

Project structure

The project is planned to run for six months. During this period, the following partners will work together on the requirements analysis, design and demonstration of the optical measurement system.

Results

The project focused on the precise, non-contact measurement of the distance between the rotor and stator of an axial flux motor. For this purpose, a specially developed micro-measuring probe was applied to an OCT fiber (optical coherence tomography) using 3D printing. With this prototype, the required measurement tolerances were successfully met and demonstrated. A brief overview can be found in the following set of slides:
