#New nanomaterial introduced into electrical machines Lappeenranta University of Technology in Finland has constructed the world's first prototype electrical motor using carbon nanotube yarn in the motor windings.
The presently most electrically conductive carbon nanotube yarn replaces usual copper wires in the windings. The motor prototype is built by the LUT Electrical engineering group as a start towards lightweight efficient electric drives.
to this end one of the objectives is to find higher-conductivity wires for the windings.
Thus future windings made of CNTS may have a double conductivity compared with the present-day copper windings.
If we keep the electrical machine design parameters unchanged and only replace copper with future carbon nanotube wires it is possible to reduce the Joule losses in the windings to half of the present-day machine losses.
No definite upper limit for the conductivity Traditionally the windings in electrical machines are made of copper which has the second best conductivity of metals at room temperature.
Despite the high conductivity of copper a large proportion of the electrical machine losses occur in the copper windings.
All these use copper in the windings. Consequently finding a more efficient material to replace the copper conductors would lead to major changes in the industry tells Professor Pyrh nen.

cramped cursive as a result of degenerating motor control is a common symptom of Parkinson's disease. Known as micrographia, this condition can often lead people to put down their pens forever,
Standard methods are either to use a electromagnetic coil, for example, where a high current produces a magnetic field,
which offer the major novelty that the different magnetic states unlike the electromagnetic coil can be maintained without requiring a continuous flow of current
As a result they are dependent on other devices and equipment, such as electric motors or pneumatics they tend to be heavy, relatively inflexible, at times loud,

smooth motor control that people have over their natural limbs. Now, a team of researchers says the members have solved part of the problem of smooth motor control by connecting an artificial limb to a different part of the brain.
Previous designs for mind-controlled prostheses linked the artificial limb to either the person's motor cortex or the individual's premotor cortex

Dan Moran, associate professor of biomedical engineering at Washington University in St louis, said he was a bit skeptical that the new prosthesis provided any finer motor control than already-developed methods of connecting with bionic arms through motor and premotor cortexes.
