In-wheel-motor-drive electric vehicles have attracted enormous attention due to its potentials of improving vehicle performance and safety. Road surface roughness results in forced vibration in-wheel-motor (IWM) thus aggravates the unbalanced magnetic force (UEMF) between rotor stator. This can further compromise vertical longitudinal dynamics. paper presents a comprehensive study reveal couple...

This paper describes an infrared-sensing running wheel (ISRW) system for the quantitative measurement of effective exercise activity in rats. The ISRW system provides superior exercise training compared with commercially available traditional animal running platforms. Four infrared (IR) light-emitting diode/detector pairs embedded around the rim of the wheel detect the rat's real-time position;...

Obesity increases the risks to motor vehicle occupants of some types of injury in crashes. The effects of obesity on injury causation are not well understood and current prevention efforts do not effectively address the increased vulnerability of individuals with high body mass index (BMI). Proximity to the steering wheel has been associated with increased risk due to airbag deployment, and the...

Hunting is a flutter associated with the synchronous speed that gives rise to the gyro drifting errors and may cause objectionable time-displacement errors in video head wheel drives and other precision scanning systems. In this paper, dynamic characteristics of permanent Magnet hysteresis motors are presented and hunting is explained. New damping techniques have been developed using optimi...

In this study, a method for estimating the efficiency of electric bicycle power train systems consisting typical components, such as an motor, gears, sprockets, and chains is presented. order to calculate system, relationship between drive motor torque road-load that exerted on rear wheel was derived, considering kinematic inertia effects friction losses transmission elements. Among factors inf...

Background: Huntington's disease (HD) is a neurodegenerative disorder predominantly affecting the cerebral cortex and striatum. Transgenic mice (R6/1 line), expressing a CAG repeat encoding an expanded polyglutamine tract in the N-terminus of the huntingtin protein, closely model HD. We have previously shown that environmental enrichment of these HD mice delays the onset of motor deficits. Furt...

Mobile Robots are used to venture through types of environments where wheel slip is a threat. Wheel slip is a hazard to mobile robots in that it introduces error in dead reckoning measurement and in some instances causes the robot to halt is forward progress. To compensate for traction loss several methods are used to determine the terrain characteristics. One of these methods is Pacejka’s Tire...

Loose clothing worn by Indian women get accidently entangled in moving wheel of motor bike or crop thresher and cause accidental strangulation. This study is about the patients admitted in department of otorhinolaryngology with history of accidental strangulation due to long scarf. This study showed that women in rural area are at risk of accidental strangulation due to long scarf getting entra...

This paper presents the design optimization of axial flux surface mounted Permanent Magnet Brushless DC motor based on genetic algorithm for an electrical vehicle application. The rating of the motor calculated form vehicle dynamics is 250 W, 150 rpm. The axial flux surface mounted Permanent Magnet Brushless DC (PMBLDC) motor was designed to fit in the rim of the wheel. There are several design...

The four-wheel-drive electric vehicle's traction chain is powered by four permanent-magnet synchronous motors (PMSM), a single three-phase, five-leg inverter (FLI). In order to achieve the behavior of mechanical differential and require parallel wheel-motors turn at identical or different speeds, using this structure, an independent control applied on each driving wheel. For particular there sh...
