News about Scitation

In December 2016 Scitation will launch with a new design, enhanced navigation and a much improved user experience.

5.Speed control of motors having stators with continuous fields can be accomplished by varying armature voltage via a reversing thyristror converter. If the rotor of such a motor is fitted directly to the periphery of a mill drum, then currently used mechanical transmissions, such as gears and couplings, are completely dispensable. A recent review of dc motor driven grinding mills in the cement and mineral industries has been published by A. C. Spurgeon in Elec. Eng. (Australia) 47, 34 (1970).
6.We limit our discussion to coils wound with wire or not too thin tape; e.g., single or multiple wires of Nb‐Ti or Nb‐Ti rich alloys imbedded in a matrix of copper for purposes of stabilization. In the case of very thin tape, such as strip, diamagnetic supercurrents result, according to Graham and Hart, in distortion of the local magnetic field seen by the windings, and the uniform current density assumption is no longer strictly valid; C. D. Graham and H. R. Hart, Proc. Int. Cryog. Eng. Conf., Kyoto, Japan, 1967, 101 (1968).

10.We note here that Day has made his calculations in emu cgs units, and therefore a factor of 10 has to be introduced in Eq. (7) if the currents are expressed in amperes.
