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.
