EMF

Electromotoric force (electric/mechanic transformer)

 Description The Rotational EMF (or EMF) component transforms electrical energy into rotational mechanical energy. It is used as a basic building block for an electrical motor. The mechanical connector, flange, can be connected to rotational mechanical components.
 Equations $i={i}_{p}=-{i}_{n}$ $v={v}_{p}-{v}_{n}=kw$ $w=\stackrel{.}{\mathrm{\phi }}$ $\mathrm{\phi }={\mathrm{\phi }}_{\mathrm{flange}}-{\mathrm{\phi }}_{\mathrm{internal}}$ ${\mathrm{\tau }}_{\mathrm{flange}}=-ki$

Variables

 Name Units Description Modelica ID $v$ $V$ Voltage drop between the two pins v ${v}_{x}$ $V$ Voltage at pin $x$, $x\in \left\{n,p\right\}$ x.v $i$ $A$ Current flowing from positive to negative pin i ${i}_{x}$ $A$ Current into pin $x$, $x\in \left\{n,p\right\}$ x.i $\mathrm{\phi }$ $\mathrm{rad}$ Angle of shaft flange with respect to support phi $w$ $\frac{\mathrm{rad}}{s}$ Angular velocity of flange relative to support w
