‘Permanent Magnets’

An Engineeringtalk guide

Start with the news release MX7 grinder makes tools with up to 16mm diameters from Anca Industrial Supplies, which we summarised at the time by saying "Anca's MX7 CNC grinder, which the company recently exhibited at the EMO Exhibition, can manufacture a variety of tools up to 16mm in diameter.". Several months prior to that, we featured the news release AC drives permit wider use of magnet motors from Parker Hannifin - Electromechanical and Drives Division: "Parker Hannifin has launched a range of AC drives that allows energy-efficient permanent magnet motors to be used in a wide range of pump, fan and compressor applications. ".

In October 2009, we covered the news from PennEngineering - take a look at Captive-screw products include UL-approved types which says: "The expanded range of PEM self-clinching captive-panel-screw products includes several UL-approved types designed for tool-only operation. ".

Take a look also at the news release from ARRK Australia and New Zealand, ARRK SLS prototypes available in range of colours, as well as Pressure-blocking connector withstands 10,000psi from ITT Interconnect Solutions, and Stepper motors available with adaptable shaft from Astrosyn International Technology.
