Transformation 1 is between the motor and gearbox. Transformation 2 is between the gearbox and the drive mechanism.  A transformation can be used to simulate a coupling, transmission shaft, second gearbox, etc.  The types of transformations and their graphics representations are:

	None
	Coupling
	Gear
	Belt and Pulley

 

Coupling

Enter the coupling inputs directly, or select from the coupling database. The image below shows a coupling selected from the database.

To unlock the inputs, click the unlock button at the top right of the form. Then all inputs can be modified.

Outputs¹:

	Max output torque	Nm
	Max input speed	rpm

Notes:
¹ If any of the calculated outputs exceed their input limit, an alarm message is generated accordingly during System Check.

 

Gear

Outputs²:

	Max output torque	Nm
	Max input speed	rpm

Notes:
¹ When active, the Secondary Inputs are used to calculate the Ratio and Inertia.  Hence the Ratio and Inertia inputs are locked when the Secondary Inputs are active.
² If any of the calculated outputs exceed their input limit, an alarm message is generated accordingly during System Check.

 

Belt and Pulley

Outputs³:

	Max output torque	Nm
	Max input speed	rpm
	Max belt tensile force4	Nm

Notes:
¹ When active, the Secondary Inputs are used to calculate the Ratio and Inertia.  Hence the Ratio and Inertia inputs are locked when the Secondary Inputs are active.
² The Belt Rigidity is used to calculate the rigidity at the transformation output.  Hence the Rigidity at Output input is locked when the Belt Rigidity input is active.
³ If any of the calculated outputs exceed their input limit, an alarm message is generated accordingly during System Check.
⁴ Only applies to Belt and Pulley

Equations:

Symbol	Description	Units
JIN	Total inertia at the transformation input	kg-m2
JOUT	Inertia connected to the transformation output	kg-m2
JTransf	Inertia of transformation at input	kg-m2
TOUT	Torque at transformation output	Nm
TIN	Torque at transformation input	Nm
i	Reduction ratio	: 1
aTransf	Rotational acceleration at transformation input	rad/s2
h	Efficiency of transformation
