In this paper, dual-rotor permanent magnet induction motor(DRPMIM) is studied to improve performance of usual induction motor(IM). Two-dimensional finite element model for DRPMIM is established by Maxwell Ansoft software, and electromagnetic characters of that was analyzed.Based on the rotating coordinate system, the mathematical model concerning DRPMIM, performance curves under the different l...

Field-oriented control can be implemented using position sensors such as encoders, resolvers or Hall sensors. However, not all motor control applications require such granularity given by a resolver or encoder; and, in many cases, they do not require control at zero speed. These applications are a perfect target for using sensorless techniques in which the motor position can be estimated using ...

Deep brain stimulation in the subthalamic nucleus is an effective and safe surgical procedure that has been shown to reduce the motor dysfunction of patients with advanced Parkinson's disease. Bilateral subthalamic nucleus deep brain stimulation, however, has been associated with declines in cognitive and cognitive-motor functioning. It has been hypothesized that spread of current to nonmotor a...

Background: In everyday life, people engage in situations involving the concurrent processing of motor (balance) and cognitive tasks (i.e., "dual task situations") that result in performance declines in at least one of the given tasks. The concurrent practice of both the motor and cognitive task may counteract these performance decrements. The purpose of this study was to examine the effects of...

This paper presents the modular topologies of dual-stator dual-winding permanent magnet (PM) linear motors for compressors used in electrified transportation application. Compared to conventional PM motor compressor, proposed model is designed with same volume but a higher thrust force density and further air pressure cylinder, which are competitive compressor industry. The compact constructed ...

Dual Two-Level Inverter is an emerging Multilevel Inverter Topology which is implemented by cascading two standard TwoLevel inverters with a six-wire open-end load in between them. Space Vector PWM Technique is implemented considering its various advantages and is selected as a good performing control strategy to control the Dual-inverter. Dual Two-Level Inverter produces space vector locations...

A customized laser combiner was designed and constructed for dual channel single molecule imaging. The feasibility of a combiner-incorporated imaging system was demonstrated in studies of single molecule FRET. Distance rulers made of dual-labeled dsDNA were used to evaluate the system by determining the distance between one FRET pair. The results showed that the system is sensitive enough to di...
