Can be driven by a low voltage, the ambient temperature is lower requirements

Giant magnetostrictive material (Giant MagnetostrictiveMaterial, GMM) drive has made ​​telescopic coefficient, output power, fast response, high accuracy and other characteristics, and the ability driven by a low voltage, the ambient temperature requirements are also low. Mainly used in precision engineering fields, such as ultra-precision  air circuit breaker , robotics displacement regulators, etc., can be precise and fast positioning, increase power output, with a high application value. In practical applications, the dynamic control of the actuator between the input current and output displacement exhibit significant non-linearity and the inherent  Electric transformer  of the material brought hysteresis nature. However, the implementation is applied at a low driving current, and quasi-static, since the magnetization process GMM mandrel may be similar to a static  electric meter , it is not significant hysteresis. On this occasion, the use of a GMM in the linear region, the input current and output displacement showed a linear relationship. However, due to the linear region of the smaller range, GMM trip shorter, so in some of the larger range of travel requirements of the occasion, such as high speed milling and hybrid motor design, the input current must be increased, increasing the itinerary.
