In the paper a rotary-linear switched reluctance motor is proposed and investigated by means of advanced numerical simulations. The motor can generate two degrees of freedom movements: the same axis can both rotate and displace linearly. It is mechanically robust, simple to construct and easy to operate also in hostile automotive environment. The stator is built up modularly from precisely shifted...
In the paper a switched reluctance rotary-linear motor is proposed and investigated. It is mechanically robust, simple to construct and easy to operate also in hostile industrial and automotive environment. The stator is built up modularly from correctly shifted three usual 8 poles switched reluctance motor stators. The mover is constructed of several common 6 poles SRM rotor stacks. The motor is...
In advanced manufacturing systems complex movements are frequently needed. These can be performed by motion systems able to execute motion of several degrees of freedom. Usually each type of movement is performed by one independent electrical machine. In a more developed approach electrical machines able to perform more degrees of freedom motion are widely required. In the paper some contributions...
A special switched reluctance motor able to perform both rotary and linear motion is proposed. Due to its compact and reliable construction and to its simple control it could be used in diverse dual motion industrial applications. In the paper the construction, working principle and design of the proposed machine are detailed. Its performances are studied by means of finite elements method based numeric...
In several advanced industrial applications both rotary and linear movements are required. But in many cases, mainly due to space limitations it is difficult to use two motors to ensure the two types of motion. For such applications the rotary-linear motors are ideal solutions. The proposed switched reluctance rotary-linear motor practically combines three identical rotating motors with a linear one...
The switched reluctance machine (SRM) is considered as one of the most inherently fault tolerant electrical machines. Unfortunately despite its robustness and reliability, faults (mainly of its windings and bearings) can appear during its operation. Therefore the SRM's condition monitoring is very important mainly in those safety-critical applications where unwanted shutdowns could have catastrophic...
The switched reluctance machine (SRM) is considered to be ideal for numerous safety-critical applications (in aerospace, automotive, defense, medical, etc.) where it is desirable that the electrical drive systems to be fault tolerant. The phase independence characteristics of the SRM enable it to operate (at lower power and higher torque ripples) also under partial phase failure conditions. The paper...
Electrical machines and drives used in various safety-critical applications are of special design in order to achieve the required fault tolerance level. In the paper a novel modular fault tolerant switched reluctance machine is proposed and studied. It is proved by means of dynamic simulations that the proposed machine is able to have continuous operation also despite of five severe winding fault...
