| Abstract: | Sensorless and brushless DiG motor used for model aircraft features small size, weightless, efficient and credible. A dedicated speed-adjustment control system of the moor is designed and developed. The position detecting method for sensorless and brushless DC moor, PWM scheme, and startup strategy are analyzed in this paper. The hardware system is developed with MEGA8 single chip computer as the kernel. The schematics of critical control circuits are given and described in detail. The test results of controlling various model aircraft are illustrated. |
