We study the influence of filament elasticity on the motion of collective molecular motors. It is found that for a backbone flexibility exceeding a characteristic value (motor stiffness divided through the mean displacement between attached motors), the ability of motors to produce force reduces as compared to rigidly coupled motors, while the maximum velocity remains unchanged. The forceveloci...

Inch-worm motors achieve high linear displacements with high forces while dissipating low power. Design of a wheel to achieve angular displacement from inch-worm motors is described. Test structures are then suggested to measure unknown parameters and determine how best to build wheels for a microvehicle. Conclusions and future work are then discussed.

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...

-As a result of the increasing use of electronic devices and other non-linear loads, the wave-forms of the electricity supply voltage are being distorted and inequalities are appearing between the phases. This deterioration is associated with problems of electromagnetic incompatibility and reductions in the efficiency of loads such as motors. This paper investigates the additional losses caused...

This paper presents a new controller for speed control problem of the BLDC motors. The nonlinear model of the motor is approximated by implementation of fuzzy rules. The uncertainties are considered in the fuzzy system. Using this model and linear matrix inequality (LMI) optimization, a robust controller for purpose of speed control of the motor has been designed and applied to it. The effectiv...

M38 T here are many different types of molecular motor; some of them move linearly along polymers, whereas others undergo rotary motions (Table 1). Many other nucleotidases, including tubulin, actin, chaperones and some G proteins, should perhaps be considered as molecular motors as well because the generation of mechanical strain is central to their activity. However, the primary focus of this...

Linear flux switching motors with simple passive segmented secondary, referred as Segmented Secondary Linear Flux Switching Motors (SSLFSMs), have low cost secondary and therefore are applicable to transportation systems like Maglev. However, it is shown that the SSLFSMs suffer from high thrust ripples. In this paper, minimizing SSLFSM thrust ripples besides maximizing its developed thrust are ...
