Frameless motor or alternator

A frameless motor or alternator is constituted of 2 parts : one stator and one rotor. In the case of a frameless permanent magnet AC motor, the stator is constituted of an assembly of laminations carrying a 3 phase winding inserted inside an housing. The rotor is constituted of a magnetic core carrying permanent magnets. For being operational, the 2 parts need to be integrated by the user inside its mechanics with bearing(s). The interest of frameless motors or alternators by comparison with complete housed motors with bearings, shaft, flanges, resides in the capability to achieve a compact mechatronic system without redundant parts or components and highest reliability, efficiency and accuracy. Frameless motors or alternators are particularly recommended for optimizing technically and economically the direct drive applications without gear. ALXION has a range of STK frameless torque motors for factory automation and STK frameless alternators mainly used for wind turbines.
