Segmented, modular synchronous reluctance direct-drive minimising the drive-train costs

High-torque motors in direct-drive applications are advantageous especially with regard to the current trend of compact, cost-effective system integration. This paper discusses the concept of segmenting a synchronous machine and the resulting beneficial motor modularisation. Thereby, high-efficient, inverter-driven torque motors are possible, preferably for a speed range of up to 3000 rpm. The output power can be scaled from a few kilowatt up to higher power levels. This modularised, high-efficient motor enables a new dimension of system integration for many industries and applications. The motor segmentation, furthermore, allows an overall drive system cost optimisation while reducing the maintenance intensive components. How the drive-train cost changes when using a segmented motor is compared to a conventional belt-driven system.
