Abstract(in English) | Traditionally, it has been accepted that electric motor torque and induced voltage constants are equal, but it is possible that the torque constant determined from the induced voltage constant fails to take the effects of armature reaction into consideration. This paper presents an experimental investigation of the relationship between the torque constant and the induced voltage constant in a DC shunt-wound electric motor. Results indicate that the induced voltage constant is significantly affected by the magnetic characteristics of the ferrous core, which forms the magnetic path, making it clear that the two constants are not always equal. It was confirmed that the effects of armature reaction are of variable intensity. Measurement of torque constant with a fixed armature, however, closely approximated the operating state torque constant. |
