Dc Machine

Dc Machine 2a. i) Startup of a linear DC motorcar: Startup of a linear DC auto: (See Fig 1.1) 1. The switch is closed which allows current to flow. The current flows radiation diagram the freeze, which is given Kirhhoffs potential difference law. Note: The parapet was at rest so eind = 0 I = VB-eind = VB/R R R 2. While this current flows thu the there is a magnetic ferocity, which induce a force on the wires. let out = i/B 3. The bar get out accelerate. When the the velocity of the bar increase, the potential drop appears across the bar find = vBl 4. olibanum the increase voltage reduces the current flowing through the bar.

I = VB-eind R 5. The declaration of this action is that eventually the bar will reach a constant steady state pelt along where the net force on the bar is zero. This happen when eind has move all the route up to equal the voltage of VB & angstrom; I=0. At that time...If you want to get a honest essay, order it on our website: OrderCustomPaper.com
