Researchers Combine Magnetic Materials to Increase Efficiency of Electric Motors

Nissan LEAF Under Hood 2

University of Adelaide researchers combined two magnetic materials in electric motors to increase the efficiency. The researchers used two innovative production techniques to combine soft magnetic composite (SMC) and amorphous magnetic material (AMM) to form a stator.

The stator is the stationary, magnetic part of the motor that surrounds the rotor. The researchers tested small prototypes using both of the production techniques, and the results showed a significant increase in energy efficiency. Researchers used one of the newly designed electric motors to create a patented water pump systems that has high efficiency for a variety of applications.

Near and Far Field Measurements with a Vector Network Analyzer

For optimal performance in over-the-air RF systems, antennas must meet specific requirements. Performance parameters like size, wind-loading, environmental ruggedness, transmission pattern, bandwidth, and power handling capability should be considered. Methods of measuring the transmission (or reception) pattern that determines antenna gain with a VNA will be examined in this article.
