Inhalt:
Sensorless field-oriented control (FOC) for 3-phase Brushless DC (BLDC) motors and permanent magnet synchronous motors (PMSM) requires current information. Integrated current sensing is used to improve current information and reduce component count. An additional current reconstruction algorithm is required to calculate missing current information with this approach. This paper analyzes the transient response of integrated current sensing for sensorless FOC to verify its feasibility for applications with high torque and rapid speed changes for applications such as washing machines.
