Introduction

The Motion allows you to define the motion of some bodies of the solution.

Translation type motion	Rotation type motion

• Select bodies which are moving. At least, one body must be selected.
• Motion Type: Two choices are proposed:
  • Translation

    Translation direction has to be chosen through Define/Modify Direction button:

    

  • Rotation

    Rotation axis has to be chosen through Define/Modify Axis button:

    

• Air type:

  Two choices are proposed, available for both Translation and Rotation:

  • Immersion in the air

    This air type is chosen when the moving bodies are immersed into a large air volume.

    It is mostly used for translating motion.

  • Sliding airgap

    This air type is chosen when the moving bodies are sliding with respect to the fixed part. The sliding surface is located inside the airgap and separates the airgap into two bodies: moving airgap and fixed airgap.

    The following example illustrates it:
    

    

    
    
    

    

    
    

    Sliding airgap is mostly used for rotating motion, especially for motors.

• In case of induction motor simulation, Slip value for induction motor can be entered
