On a rotary-linear switched reluctance motor

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 able to ensure both rotating and linear movement. Its complex structure is analyzed in depth by means of finite element method based three dimensional numeric field computations. The proposed rotary-linear motor is expected to be useful in diverse advanced industrial and automotive applications where both linear and rotary motion is required and the space at disposal is reduced.
