The retardation test circuit diagram is shown below. This test is used to get total stray losses like the combination of mechanical losses like windage & friction and iron losses of the DC machine. In this circuit, the A1 and A2 are armature terminals. The Retardation Test on D.C Machines ...
To effectively detect the faults of rolling element bearings under harsh working condition, an IMF-based adaptive envelope order analysis (IMF-AEOA) technique is proposed in this section. The flow chart of the IMF-AEOA is shown in Figure 1, and its principle and implementation are elaborated ...
