What is Sensorless Control for Washer Motors about?
The document discusses sensorless motor control for washing machines. It describes how sensorless field-oriented control (FOC) of permanent magnet synchronous motors (PMSM) can enable direct drive of washing machine drums without position sensors. The FOC algorithm estimates rotor position indirectly based on stator current and voltage measurements. This allows sinusoidal current waveforms for smooth torque and field weakening for high speeds. The algorithm is implemented digitally using a motion control en
