Abstract

Permanent magnet brushless motor is widely used in industrial drive applications due to high efficiency, high power ratio, and easy maintenance. Position and speed sensors required in this dolor increase the drive cost, and reduce the application range. Some papers present the sensorless speed control using DSP with a high processing performance. However, DSP increases the cost, and makes the implementation difficult. This study has performed the sensorless speed control with a microprocessor system which can be easily accessed.
