"Unless we should make a radical departure in the character of the electric currents employed, iron will be indispensable.Yet the advantages it offers are only apparent. So long as we use feeble magnetic forces it is by far superior to any other material; but if we find ways of producing great magnetic forces, then better results will be attainable without it.

Agreed.  Thus my previous recommendation Thane at least consider a dual rotor, axial flux design.  The result is a small reduction in flux but a huge reduction in core/rotor drag = greater efficiency.

Wait a minute, should not have a magnetic connection between the magnets and the motor shaft to create the effect of regenerative acceleration?

RE Telsa Quote first published in June 1900 by Century Illustrated Magazine
_{In fact I have already produced electric transformers in which no iron is employed, and which are capable of performing ten times as much work per pound of weight as those with iron. This result is attained by using electric currents of a very high rate of vibration, produced in a novel way, instead of the ordinary currents now employed in the industries."}


Tesla's comment was really an observation, that less inductance is required in a transformer at higher frequencies, to handle a given level of power, than at lower frequencies. High frequencies were extremely difficult to work with in Tesla's day.  With today's high power, high frequency semiconductors, such tasks are now commonplace.  Modern PC's have switching power supplies, operating at high frequencies, so the transformer itself, can be tiny and lightweight.  Tesla's vision fullfilled.

hoptoad,

thank you for this motor-info. Very interesting spec.
Since you have brought up this info here my question would be : is this motor - according to your knowledge -  commercially available or was it just a prototype which they do not sell on a commercial basis.

Any additional links you have ?

Unfortunately Kator01 I've been unable to find any more relevant information about this particular motor. I don't know whether this has been produced commercially or not. Every search I've done so far leads to a dead end.

Cheers
