US 2024/0266931 A1 · METHODS AND APPARATUS FOR MANUFACTURING A STATOR FOR AN ELECTRIC AIRCRAFT MOTOR

Abstract

An apparatus for manufacturing a stator for an electric aircraft motor includes a manufacturing device. The manufacturing device includes a work holding device configured to hold at least one segment of teeth. The manufacturing device also includes a winding device configured to create a modular winding set in the at least one segment of teeth. Creating the modular winding set includes acquiring a continuous conductor and winding a continuous conducting coil on each tooth of the plurality of teeth held by the work holding device using the continuous conductor. The manufacturing device may also include an installation device configured to install a plurality of segments of teeth into the stator.
