Remanence, coercivity and permeability are fundamental concepts to understanding the magnetic properties of permanent magnets. There is much to know about them and other key aspects of magnetics technology that is important for sophisticated design […]
Servo motors are at the heart of modern gimbals, allowing them to move and position components in tracking and communication equipment for military and surveillance devices, navigation systems, industrial robots as well as drones and […]
Ducommun, a defense and industrial manufacturer based in southern California, has acquired Magnetic Seal Corporation, a pioneering developer of engineered magnetic seals for aerospace and defense applications. The price was about $69.5 million. According to […]
Constant velocity control is essential for many advanced industrial processes, but traditional motor designs give rise to cogging forces which generate ripples in the motor velocity. Precision motors from Kovery of South Korea use innovative […]
Permanent magnets (PM) are the heart of the drive systems used in the e-Mobility industry. The stronger the magnet is, the higher the higher the motor’s output and the smaller and lighter the motor can be built. But a powerful magnet must also be able to resist demagnetization by heat or a magnetic opposite field. The Dutch company Bakker Magnetics uses two new techniques with which permanent magnets can be produced even stronger and more robust: Grain Boundary Diffusion (GBD) and Grain Refining Technology (GRT). Major advantage: less Heavy Rare Earth Elements (HREE) are used. […]
Dexter Magnetic Technologies is planning to move to new, expanded headquarters in Elk Grove, Illinois. The new site is about 2.5 miles north from its present location northwest of Chicago. According to an article in the Chicago […]
Littelfuse has expanded its portfolio of reed relays to extend voltage capabilities of its hermetically sealed switches for systems requiring no-leakage current or operating in harsh environments requiring galvanic insulation. Packaged in single-in-line and dual-in-line configurations, […]
