Digital guide

Product Name: AC Induction Motor (Drum Drive Motor)
Model Series: AM-S975 Series — Washing Machine Drive Motor
Applicable Products: AEG Front-Loading Washing Machines (Lavamat, ÖKOMix, L6/L7/L8 series)

Product Description:
The AEG AM-S975-103 is a variable-speed AC induction motor (or triac-controlled motor) used as the drum drive motor in AEG front-loading washing machines. It provides precise speed control for wash, rinse, and spin phases, replacing older fixed-speed universal motors. It is a direct-drive or belt-drive motor depending on the machine variant.
