Implementation and Study of a PMSM Drive with Sensorless Field-Oriented Control for a Fan Application

The paper presents an application of sensorless field-oriented control of a permanent magnet synchronous motor (PMSM) for a high-efficiency electrical drive of industrial fans. Generally, the application requires high efficiency due to the continuous operation of ventilation systems. The replacement of the traditionally used induction motors with permanent magnet synchronous motors and an electronic converter aims to reduce electricity costs for ventilation in industrial enterprises in the long term.
