<p>This paper proposes a linear switched reluctance motor (LSRM) to replace the conventional serving that is used in food and beverage (F&amp;B) applications such as pack of sushi carbonated drinks. This method no longer practical it requires lot space which will affect costing productivity. It’s also has another disadvantage, needs frequent maintenance rotational motor, gear, limit s...
In this study, a double-sided linear switched reluctance motor (LSRM) drive was investigated as an alternative actuator for vertical linear transportation applications such as a linear elevator door, hospital and subway doors which move linearly and where accurate position control and rapid response is requested. A prototype sliding elevator door that is focused on a home elevator with LSRMs is...
Introduction: Investigating the factors affecting motor development is very important in identifying the causes of motor developmental delay for parents and occupational therapists in the development of pediatric treatment. This study aims to model dynamic factors affecting fine motor development milestones of 9-12 months old infants. Method: in this study 283 children were screened by age and ...
The Electromagnetic Aircraft Launch System (EMALS) is being developed utilizing electrical and electronic technologies. EMALS is emerging in order to replace the existing steam catapult on naval carriers. Recently, the double-sided linear launcher has drawn increasing attention of researchers. This paper presents the design and analysis of the Linear Hybrid Reluctance Motor (LHRM). This new mot...
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 ...
The purpose of this study was to determine the relationship between movement motivation and motor development in infants with and without the experience of kindergarten. The population of this study included all parents with infantchr('39')s boys with 10 to 11 month in Tehran. Among them, 150 infants with and 150 infants without the experience of kindergarten using the multi-stage random sampli...
nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...
Initially, linear motors have been particularly dedicated to transportation systems. Nowadays, linear motors are meant to replace a system using a rotating motor and a transmission to realize a linear movement. With linear motors the performances increase considerably since the mechanical limitations are removed. This leads to a better precision, a higher acceleration and a higher speed of the ...
The motor/guide contact evaluation is one of the most important processes to get high performances of the linear ultrasonic motor. In this paper, displacement power spectrum is proposed and investigated to evaluate the motor/guide contact of rectangular plate linear ultrasonic motor. First, the effect
