BLDC motor is widely used as a servo motor, because it has efficiency, high power ratio, low inertia, and low maintenance. However, BLDC motor generally needs position and speed sensors to synchronize the phase angle that it raises the system costs and complexity. This paper describes a simple sensor-less speed control of BLDC motor with using back EMF signal. Adaptive PID speed control algorithm was developed and verified for wide speed ranges.

The artificial arm is developed for medical trainees to exercise pulsimeter and tonometer. The arm has a pressure gage to monitor the cuff pressure. If the cuff pressure changes to the blood pressure range which is set by external controller, a audio speaker which is driven by MP3 chip plays the Korotkoff sounds an artificial vane which is located at the wrist which is driven by a solenoid actuator beats. The touch screen type LCD monitor is adopted for external controller and the control system can set not only the blood pressure but also various types of disease. The artificial arm which is developed in this paper can be applied for training the student nurses.
