where T e is the machine electromagnetic torque, n ph is the number of phases, p is the number of pole-pairs, λ pm is the flux linkage from the permanent magnets, I s is the machine current amplitude, and φ i is the internal power factor angle (angle between current and internal ...
For instance, some meter type photometers and many transistor radios contain very strong unshielded permanent magnets. An instrument known as a pocket magnetometer can be used to discover or determine the magnitude and polarity of such disturbing residual magnetic fields. The calibrated magnetometer is...
A Review of Modern Materials of Permanent MagnetsTushar Deep SaxenaJETIR(www.jetir.org)
Microstructures and magnetic domains of precipitation hardened Sm(Co0.653Fe0.257Cu0.066Zr0.024)7.3 permanent magnets were investigated using a high-voltage electron microscope. The cellular microstructures controlled by step aging were clearly observed on atomic scale by high-voltage HREM. It was found ...
