Performance
Scientific paper
The purpose of this paper is to introduce the concept of a Locking Lorentz Slide. Lorentz Slide actuators, which are based on the Lorentz force principal of physics and are also called Voice Coils, have earned wide-spread use in the aerospace industry because of their superior performance (precision, force, stroke, wide temperature range including cryogenics, reliability and compactness). NASA has particularly favored these devices in their space telescopes and scientific instruments. Up to now 'Voice Coils' have had to keep power on to hold position, which is limiting in many space applications. NASA, however, has found what promises to be a simple, innovative work-around with its Locking Lorentz Slide approach. This paper is an introduction to that concept and its possibilities, so, in this paper, the Locking Lorentz Slide is described, its principles of operation explained an its expected performance given. Since NASA is embarking on a development effort for this actuator more technical papers detailing hardware, tests and detailed analysis will follow.
