EMF

Electromotoric force (electric/mechanic transformer)

Modelica Standard Library

	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
	$i = i_{p} = - i_{n}$ $v = v_{p} - v_{n} = k w$ $w = \overset{&period;}{φ}$ $φ = φ_{flange} - φ_{internal}$ $τ_{flange} = - k i$

Variables

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

Connections

Name	Description	Modelica ID
$p$	Positive pin	p
$n$	Negative pin	n
$flange$	Rotational flange	flange
$support$	Support/housing of emf shaft	support

Parameters
