The most efficient motors available in the market today are in the range of 95 to 98 percent effective in converting electrical input into mechanical output — according to the present configurations and the laws of physics upon which they are founded. Building on that foundation, any gains in efficiency will be just a few percent at most. In his DVD presentation, drawing on 30 years of his own research and development, Peter Lindemann explains in simple terms what back EMF is, and how one can build motors and generators that do not involve back-EMF. He asserts that such designs can improve upon the most effective motors of today by many-fold, not just a few percent. The best illustration of back EMF is the fact that if you turn the shaft on a typical motor, it turns into a generator, producing electricity. Lindemann points out that when electricity is input into a motor that even though net motive force is achieved, that at the same time electricity is being produced that works against the input electrical force. This is back EMF. Present physics describes it as an inescapable fact. Pointing to the seminal work of Bob Teal in the 1970s, Lindemann points out that it is possible to create a motor that does not produce back EMF. Simply put, this is accomplished by using a piece of iron instead of a magnet to go into an electromagnetic coil. It is even possible to wire the coil circuit such that rather than producing back EMF, the collapsing magnetic field can actually be picked up separate from the input electricity, rather than fighting against the input electricity. Lindemann also points to the work done by John Bedini to develop simple circuitry by which what used to be back EMF can be harnessed for use, rather than working against the motor system. He also draws from the work of Roger Andrews who has patented several „executive toys“ (desktop demo models) that run for much longer than they „should“. Lindemann then explains some motor designs he himself has come up with, including a prototype he build in the early 1980s that had tremendous torque. He has not had the resources to develop his later designs (e.g. the Lindemann Solenoid Engine), but is confident that they are an improvement on the earlier prototype he built, and that they will continue to push forward a new understanding of motor possibilities.
