This paper analyzed the effect of temperature on the permanent magnet flux and output torque. The major parameter which will impact the torque control accuracy of a surface mounted permanent magnet motor is the variation of the permanent magnet temperature. In addition, the temperature variation of the permanent magnet will also influence the maximum torque per ampere of the motor. To analyze t...

The purpose of the work is organization six-cylinder diesel engines (with a power 116 and 156 kW) working process with exhaust gas recirculation. following systems components were used in experimental configuration engine: Common Rail BOSСH accumulator fuel injection system an pressure 140 MPa equipped electro-hydraulic injectors 7-hole nozzle 500 mm3 hydraulic flow; direct MOTORPAL pump maximu...

In the field of water distribution systems the EPANET 2 toolkit is considered nowadays the industry standard for hydraulic modelling. Unfortunately, the design and programming model of EPANET 2 have some limitations that make any attempt to extend its hydraulic solver, add new functionalities or improve performance difficult to achieve and time consuming. A new software toolkit for water distri...

Engine is the main source of vibration that generates unwanted noise and vehicle chassis. Especially, in submarine applications, radiation signatures can be detected at some distance away from using a sonar array. Thus quiet operation crucial for submarine’s survivability. This study addresses reduction force transmissibility originating engines transmitted to hull through engine mounts. An ine...

Abstract This paper demonstrates the importance of assessing whirl flutter stability propeller configurations with a detailed aeroelastic model instead local pylon models. Especially growing use electric motors for propulsion in air taxis and commuter aircraft becomes an important mode instability. These often include which are powered by lightweight located at remote locations, e.g. wing tip. ...
