Immunity of Integrated Drive System, Effects of Radiated and Conducted Emission
In this paper the problems associated with immunity
of embedded systems used in Motor-Drive systems are investigated
and appropriate solutions are presented. Integration of VSD motor
systems (Integral Motor) while partially reducing some of these
effects, adds to immunity problem of their embedded systems. Fail
safe operation of an Integral Motor in arduous industrial
environments is considered. In this paper an integral motor with a
unique design is proposed to overcome critical issues such as heat,
vibration and electromagnetic interference which are damaging to
sensitive electronics without requirement of any additional cooling
system. Advantages of the proposed Integral motor are compactness
of combo motor and drive system with no external cabling/wiring.
This motor provides a perfect shielding for least amount of radiated
emission. It has an inbuilt filter for EMC compliance and has been
designed to provide lower EMC noise for immunity of the internal
electronics as well as the other neighbouring systems.
