This paper presents the servomotor structure suitable for sensorless drives based on high-frequency injection method. The position estimation accuracy is related to saliency ratio of motor. Although motor with increasing load has been reported, mechanism phenomenon not explained.

In electrical engineering the technical terms “servomotor” and “servo control system” are used since long decades ago. They generally accepted wide-range denominations worldwide in scientific papers, books, advertisements other publications. words, above two become somewhat self-understanding incontestable parts of our language. However, this paper emphasizes idea to discuss exact real meaning ...

This paper presents an efficient servomotor-aided calibration method for the triaxial gyroscope. The entire process only requires approximately one minute, and does not require high-precision equipment. is based on idea that measurement of gyroscope should be equal to rotation speed servomotor. A six-observation experimental design proposed minimize maximum variance estimated scale factors bias...

Elastic tendons can act as muscle power amplifiers or energy-conserving springs during locomotion. We used an in situ muscle-tendon preparation to examine the mechanical function of tendons during lengthening contractions, when muscles absorb energy. Force, length, and power were measured in the lateral gastrocnemius muscle of wild turkeys. Sonomicrometry was used to measure muscle fascicle len...
