| Abstract: | DC machines have good performances and are widely used in industry applications. However, their spark and even flash generated in the process of mechanically hard commutation are the main imputation to cause the brushes and commutators damage. An analysis of novel mechanism of DC machines with soft commutation is presented in this paper. This prevents the spark and flash generation which normally occurs in traditional DC machines with mechanically hard commutation. |
