Sinusoidal Rotational Velocity Source

Source of sinusoidal angular velocity.

sinusoidal rotational velocity source

Description

The Sinusoidal Rotational Velocity Source unit is a constant offset sinusoidal angular velocity source.

Relative angular velocity between stator and rotor:

where

  • - is the relative angular velocity;

  • - is the absolute angular velocity at the rotor boundary;

  • - absolute angular velocity at the stator boundary.

The governing equation for sinusoidal angular velocity:

where

  • - is the output angular velocity;

  • - output velocity offset;

  • - peak amplitude of the sinusoid;

  • - frequency of the sinusoid in Hz;

  • - time;

  • - phase shift of the sinusoid.
