RL78/G1G
Sensorless Speed control of 120-degree conducting controlled permanent
magnetic synchronous motor (Implementation)
Summary
This application note aims at explains sample programs driving a permanent magnetic synchronous motor in the 120-
degree conducting method using the RL78/G1G microcontroller.
These control programs are only to be used as reference and Renesas Electronics Corporation does not guarantee the
operations. Please use them after carrying out a thorough evaluation in a suitable environment.
