Publication number: 20080111429Abstract: An apparatus monitors and controls application of three phases of alternating voltage to a load by detecting the sequence of the three phases. A switch module is operated, in response to the detected sequence, to ensure that the three phases are properly applied to the load, even if the utility lines are improperly connected. The monitoring also senses loss of a phase in which case the switch module disconnects the application of electricity to the load. The apparatus is capable of being used with different loads that operate at different peak to peak levels of alternating voltage.Type: ApplicationFiled: November 9, 2006Publication date: May 15, 2008Inventor: Shane M.

Publication number: 20080111430Abstract: In a linear motor (1), the detent force is reduced by the height of the iron poles (522) being selected differently in the two outer regions of the coil set, preferably by a gradual reduction of the height of the iron poles (522) towards the ends of the stator (2). In combination with a slight inclination of the magnets, the detent forces are further minimized, with negligible losses of the propulsive force. The exact dimensioning of the iron poles (522) is dependent inter alia on the dimensioning of the coils (51) and other characteristics of the linear motor (1) as a whole, and can be found and optimized by simulations. Here, an optimum is sought between as great a reduction as possible of the detent force amplitude and as high a propulsive force as possible.Type: ApplicationFiled: October 24, 2007Publication date: May 15, 2008Inventor: Alois Jenny
