Additive Drives GmbH’s Post

More than 10% increase in continuous performance Additive Drives and Daikin Chemicals recently presented the first results of their joint development activities at the #EDPC in Regensburg: increasing the copper fill factor in electric motors while reducing partial discharge. One of the challenges in developing long-life, performing electric motors, especially for use in electric aircraft, is partial discharge. The effect of partial discharge between the individual conductors will damage the insulation, and significantly reduce the life of the electric motor. Additive Drives takes the phenomenon of partial discharge into account when developing new electric motors. The Partial Discharge Inception Voltage (#PDIV) level can be increased by adjusting the wiring. For this purpose, the winding design is optimized and validated for PD using our in-house simulation tools. In addition, PFA insulated magnet wire is used to achieve the best possible results. Side by side functional testing demonstrated a PDIV level consistently higher compared to the incumbent insulation materials. Consequently and compared to PAI enamel wire, the insulation thickness could be reduced by 50%, resulting in a significantly higher copper fill factor in the slot and an increase in the continuous power of the motor by more than 10%. At the same time, the efficiency of the motor is significantly improved. This technology can be used in a variety of ways and opens up new areas in the field of high-performance electric motors: - 800+ V for passenger cars, commercial vehicles and heavy trucks - Durable rail and traction drives - Powerful aviation drives The in-house production of wires enables particularly fast prototyping and rapid validation of the concepts. Processing on standard equipment guarantees the suitability of scaling the production process. For further information please visit www.additive-drives.de or contact Philipp Arnold.
