Molecular motors are found throughout the cells of the human body and have many different and important roles. These micromachines move along filament tracks and have the ability to convert chemical energy into mechanical work that powers cellular motility. Different types of motors are characterized by different duty ratios, which is the fraction of time that a motor is attached to its filamen...

The paper covers state of the art and latest development of piezoelectric motors at Kaunas University of Technology (Lithuania), that are related to the R&D of laser scanning and deflecting devices, measuring systems, nano-resolution positioning devices on the plane, various applications including teaching aids for Mechatronics studies and even “intelligent” toys. All presented motors are oneor...

Kinesin motors drive the long-distance anterograde transport of cellular components along microtubule tracks. Kinesin-dependent transport plays a critical role in neurogenesis and neuronal function due to the large distance separating the soma and nerve terminal. The fate of kinesin motors after delivery of their cargoes is unknown but has been postulated to involve degradation at the nerve ter...

Voltage fluctuation is one of the important types of power quality aspects originated from heavy fluctuating loads. This phenomenon can influence the behavior of induction motors, produce excessive vibration and increase the ohmic losses. In this paper a simplified model to evaluate the electrical characteristics of three phase induction motors under voltage fluctuation conditions will be prese...

Ultrasonic motors have been expected as a leader of new actuators since 1980th when they were invented. Author has been conducted research on analysis of characteristics of ultrasonic motors, development of novel ultrasonic motors including multi-degree-of-freedom (DOF) ultrasonic motors, and application of ultrasonic motors for robotic field. In this paper, several results are described.

in the present study, field oriented control of step motor implementation has been analyzed sothat it can make a sensorless control. efficiency and facilities of step motor is more than othertypes of electromotor. therefore, the numbers of mechanisms and different types of turning canbe made into them. also controlling these motors is easier than other available motors. steppingmotor has been d...

electric motors are the largest consumer of world electric energy, consuming more than twice as much as lighting, the next largest consumer. electric motors account for between 43 and 46% of all global electricity consumption approximately. they give rise to about 6 040 mt of co2 emissions. end‐users approximately spend usd 565 billion per year on electricity [1]. in recent years, increase in e...

We use a minimal model to study the processive motion of coupled synthetic molecular motors along a DNA track and we present data from Monte Carlo (MC) computer simulations based on this model. The model was originally proposed by Bromley et al. [HFSP J. 3, 204 (2009)] for studying the properties of a synthetic protein motor, the "Tumbleweed" (TW), and involves rigid Y-shaped motors diffusively...
