Magnetic Harmonic Drive System!

No, they're not talking about using lighter parts to 'reduce' the 'inertial mass' of the rotating members by design.  They are referring to replacing the rotating mechanical wave generator, which has mass, with a rotating electromagnetic wave generator to deform the flex spline, which eliminates the mass of the mechanical wave generator and eliminates the mass of the rotating members of the motor that drives the harmonic drive.  This has the effect of 'reducing' the overall 'inertial mass' of the harmonic drive itself, thus it's called a low inertia harmonic drive.

How is eliminating rotating mass by design not reducing the inertial mass of the rotating members by design?  What I wanted to make certain you were not trying to suggest that they were building some electronic device that by its operation reduces the inertia of some object.

I wanted to make certain you were not trying to suggest that they reduced the inertial mass just by using lighter parts.  If this was the case, then the project never would have been classified. 

Now, where did I suggest or indirectly implied that they were building an electronic device that by its operation reduces the inertia of some object?  I never suggested this, as you wrongly assert.  What I posted was taken directly from the unclassified publication itself, and I even attached a snapshot of the publication for a quick reference to support what I posted!

I did not say that you did.  I wanted to be sure that was not what you were trying to suggest, so I asked.

This is true.  However, you wrongly impied they used lighter parts by design to reduce the inertial mass of the rotating members.  Eliminating the inertial mass of the rotating members equates into a quicker response time, higher acceleration rates, and a higher COP while maintaining the high torques associated with the conventional mechanical harmonic drives.
 
This almost qualifies as a complete solid state harmonic drive, and you downplayed it by keeping it fully in the mechanical realm by suggesting the use of lighter mechanical parts to reduce the inertial mass of the rotating members by design!
