| Summary: | 碩士 === 國立交通大學 === 電控工程研究所 === 103 === BDCM position sensorless control is common in the low-cost applications. When the motor starts, the motor may run in the reverse direction. Some applications don’t allow this condition. We need to find initial position of rotor. In this thesis the initial rotor position is estimated by the current peak differences. By this method, we can start motor in clock wise direction. This paper uses sliding mode control to implement position sensorless control for ceiling fan motor. All the control are implemented and verified. The provided results are also explained.
