Sources.SpeedSource

Deprecated alias for VelocitySource.

This name is retained for backward compatibility. Use RotationalComponents.Sources.VelocitySource instead.

This component extends from RotationalComponents.Sources.VelocitySource

Usage

RotationalComponents.Sources.SpeedSource()

Parameters:

Name	Description	Units	Default value
ref_type	Type of reference signal handling	–	RotationalC....Filtered()

Connectors

• spline - This connector represents a rotational spline with angle and torque as the potential and flow variables, respectively. (Spline)

• support - This connector represents a rotational spline with angle and torque as the potential and flow variables, respectively. (Spline)

• w_ref - This connector represents a real signal as an input to a component (RealInput)

Variables

Name	Description	Units
phi_support	Absolute angle of the support spline	rad
phi	Rotation angle of spline with respect to support	rad
w	Angular velocity of spline with respect to support	rad/s
a	Angular acceleration of spline with respect to support	rad/s2
