Abstract

Angular accelerations arising about axes of inertia transverse to the rotation axis of the washing machine drum, are determined as fluctuations in the measured value of rotary speed through relocation of the sensor or actuator of a rotary sensor system. An independent claim is included for corresponding measurement instrumentation.
