| Abstract: | The application of magnetic eneoder in phase commutation control of brushless DC motor was introduced. The featm-es and principle of the magnetic encoder were described,and its resolver-to-digital converting algorithm was proposed. On the basis of principle of phase commutation control of brushless DC motor, some correlative problems emerged in system development were discussed in detail. Finally, experimental results, which demonstrate that it is feasible to apply the magnetic encoder in phase commutadon control of BLDCM, were presented. |
