DC Machine
Introduction: DC Machines form one of the varieties of electrical equipment and are extensively in use in various industrial applications like DC voltage generation, electro- plating, metal extraction, traction, steel industry, paper mills etc. While the performance analysis and design features have been considered already, given the design data, this chapter deals as to how to make drawings of parts, sub assembly and general assembly. The input data for making the CAD drawing may be in the form of wordings, sketches or both. Te following are the parts of DC machine- 1. Yoke- Housing- Casing 2. Poles- Main Poles- Inter Poles- Compensating Winding 3. Armature and Armature Winding 4. Commutator 5. Brush and Brush Holder 6. Fan 7. Bearing 8. End Shields 9. Lifting lug The general appearance (Figure-1), a dismantled view (Figure-2), an exploded view (Figure-3), a general assembly (Figure-4) and a sectional pictorial view (Figure-5) of DC Machine are given below, to familiarize
