Rotational Constant Speed

Constant speed, not dependent on torque

Modelica Standard Library

	Description
	The Rotational Constant Speed (or Constant Speed) component generates a fixed 1-D rotational constant speed at the flange.

	Equations
	$w = w_{fixed} = \overset{&period;}{φ}$ $τ = τ_{flange}$ $if Use Support Flange then τ_{support} = - τ$ $φ = φ_{flange} - {\begin{array}{c} φ_{support} & Use Support \\ 0 & otherwise \end{array}$

Variables

Name	Units	Description	Modelica ID
$φ$	$rad$	Angle of flange with respect to support	phi
$φ_{flange}$	$rad$	Angle of flange	flange.phi
$φ_{support}$	$rad$	Angle of support	support.phi
$τ$	$N m$	Accelerating torque acting at flange	tau
$τ_{flange}$	$N m$	Torque at flange	flange.tau
$τ_{support}$	$N m$	Torque at support	support.tau
$w$	$\frac{rad}{s}$	Angular velocity of flange with respect to support	w

Connections

Name	Description	Modelica ID
$flange$	Flange of shaft	flange
$support$	Conditional Support Flange	support

Parameters

Name	Default	Units	Description	Modelica ID
$w_{fixed}$	$1$	$\frac{rad}{s}$	Fixed speed	w_fixed
Use Support	$false$		True (checked) means use support flange	useSupport
