Equivalent motor mass¶
Introduced in MORe v3.1
Represents an additional motor inertia. Can be used to model the rotor inertia without explicitly modeling it in FEM.
Block diagram¶
Signal | Description |
---|---|
\(u_f\) | Filter output |
\(u_v\) | Clutch link velocity |
\(u_x\) | Clutch link position |
\(v_{fb}\) | Motor velocity. Can be used as feedback in architecture. |
\(x_{fb}\) | Motor position. Can be used as feedback in architecture. |
\(y\) | Motor output. Force acting on clutch link. |
Parameter¶
Variable | Units linear | Units rotary | Description |
---|---|---|---|
Stiffness | \(N/m\) | \(Nm/rad\) | Clutch stiffness |
Damping | \(N s/m\) | \(Nm s/rad\) | Clutch damping |
Inertia | \(kg\) | \(kg m^2\) | Rotor Inertia |
Spindle pitch | \(-\) | \(m\) | Ball screw spindle pitch. Used for setpoint animation |
Clutch¶
Link selection to represent the motor. The controller output (force/torque) will be applied to the selected link.
