Rotational Speed (Controlled)

Purpose

Maintain variable rotational speed

Library

Mechanical / Rotational / Sources

Description

The Controlled Rotational Speed maintains a variable angular speed between its two flanges regardless of the torque required. The speed is considered positive at the flange marked with a “+”. The momentary speed is determined by the signal fed into the input of the component.

Note

A speed source may not be short-circuited or connected in parallel with other speed sources, nor may a speed source directly drive an inertia.

Parameters

Second flange

Controls whether the second flange is accessible or connected to the rotational reference frame.

Allow state-space inlining

For expert use only! When set to on and the input signal is a linear combination of mechanical measurements, PLECS will eliminate the input variable from the state-space equations and substitute it with the corresponding output variables. The default is off.

Probe Signals

Torque

The generated torque \(\tau\) flowing from the unmarked to the marked flange, in newton-meters \((\mathrm{Nm})\).

Speed

The angular speed, in \(\left( \frac{\mathrm{rad}}{\mathrm{s}} \right)\).
