| Abstract: | Due to the complexity of air gap magnetic field for the permanent magnet direct current motor,the calculation of commutation performances is one of the problems which are difficult to overcome.In this paper,taking the effects of brushe shift into consideration,the calculation models of no load and load magnetic fields are given and the expression of air gap magnetic field at the surface of armature is deduced,on basis of which the commutation performances can be obtained. |
| Keywords: | Permanent magnet direct current motor Air gap magnetic field Calculation of commutation performances |
