Keywords:single shunt  sensorless  vector control 

In this document, Renesas Electronics presents the RX62T single shunt sensorless vector control solution, which has been implemented on RX62T evaluation kit with single shunt current measurement.

It describes the evaluation kit hardware platform, single shunt current measurement, motor phase current reconstruction method, single shunt sensorless vector control strategy, and software implementation.

Usually, three shunt current sensors are used to measure motor phase currents for current control and flux observer, which results in more hardware cost. In this application note, a complete and unique motor phase current reconstruction method is introduced.
