We see from your search that you're looking for information on the term "Permanent Magnet",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release Test rigs upgrade motor repair services from
Anstee Ware Group, which we summarised at the time by saying "Permanent magnet motor repair and calibration service covers all manufacturers, makes and sizes, and includes the complete overhaul of motors, gearboxes and pumps".
A couple of weeks before,
we featured the news release DC drive technique eases maintenance from
CP Automation: "CP Automation's DC drives technique dispenses with the use of a 'keeper', which normally acts as a substitute for the armature in the servicing procedure".
In January 2008, we covered the news from Total Motion Systems
- take a look at Website receives motion control upgrade
which says: "Total Motion Systems' (TMS) website now shows its complete range of products and services for the motion control industry".
Take a look also at the news release from SSD Parvex, Torque motors are made for extruders,
as well as Permanent magnet motors promise smooth rotation from Parvalux Electric Motors,
and Software helps develop magnetic innovations from Vector Fields.
