In this paper a new structure of the linear transverse flux machine will be presented. It is a combination of a hybrid linear stepper motor and of a linear transverse flux machine with permanent magnets. The design algorithm of the proposed structure will be presented in detail. Upon this algorithm a motor required by a specific application was designed. Several programming packages were used d...

Nowadays, piezoelectric motors are used as amplifiers and receivers. The principle of operation stepper motors, which is the subject article, explains a small centrifugal inertial moving system. Piezoelectric measurement technology good tool that can be under conditions with some extreme dynamics, temperature geometry applications difficult to measure devices in our daily measurements. effect w...

<img src="blob:http://ijra.iaescore.com/f3842e5c-715f-4e1e-9ffd-952309f5ccb1" alt="" />Stepper motors are broadly utilized in actual systems, which marked by non-linear parameters such as internal, external noises and uncertainties from wireless network. As well, a suitable controller is required when the problem to track target signal. In this paper, robust based on model reference inves...

Developments in electronic and computer technology area have increased the importance of computer aided control. The control systems in frequent use are microprocessor control, microcontroller control and the computer aided control. Computer aided control can be implemented by serial port, parallel port or control cards prepared by special purposes. In this paper, a control card to use in compu...

This paper presents MOSFET based analog to digital converter which is simple in design, has high resolution, and conversion rate better than dual slope ADC. It has no DAC which will limit the performance, no error in conversion, can operate for wide range of inputs and never become unstable. One of the industrial applications, where the proposed high resolution MOSFET ADC can be used is, for th...

Escherichia coli and other bacteria use rotating helical filaments to swim. Each cell typically has about four filaments, which bundle or disperse depending on the sense of motor rotation. To study the bundling process, we built a macroscopic scale model consisting of stepper motor-driven polymer helices in a tank filled with a high-viscosity silicone oil. The Reynolds number, the ratio of visc...

In vitro mechanical cell stimulators are used for the study of the effect of mechanical stimulation on anchorage-dependent cells. We developed a new mechanical cell stimulator, which uses stepper motor technology and computer control to achieve a high degree of accuracy and repeatability. This device also uses high-performance plastic components that have been shown to be noncytotoxic, dimensio...
