A Novel Design Technique for Brushless DC Motor in Wireless Medical Applications

Abstract

The wireless technology plays a vital role in various fields such as aerospace, home appliances and global positioning system etc. This is important, especially in a biomedical wireless communication, which communicates wirelessly with patient control device for monitoring and external communication. It reduces the invasiveness range of test and discomfort of some invasive procedure such as endoscopy etc. Wireless communication has taken for supporting mobility while monitoring vital body function in hospitals, clinical diagnosis, remote repository system and gastrointestinal tract exploration etc. The Brushless DC motor (BLDC) is ideal for these applications of wireless communication due to their easiness of control, low maintenance, high efficiency and reliability. The BLDC motor placed in these devices, which allow variable speed and motion to acquiring the required data. In this paper, a novel control strategy for controlling the speed of BLDC motor, which fill the need of medical analyzer, is presented. The results are compared with other recently published work in terms of various performance specifications.
