How to convert a factory-manufactured induction motor into rotary-linear motor ? Part 1 Constructional issues

Induction motors with two degrees of freedom are unconventional drives offering broader possibilities of different movements than traditional drives. There is general opinion that construction of a machine with 2 degrees of freedom (2DoF machine) is much more complicated and expensive than a machine with one degree of freedom. In the paper the authors show that it is possible to construct in easy way (even in an university laboratory workshop) a 2DoF 2-module induction motor using components of a factory-manufactured 3-phase squirrel-cage motor. The presented solution is one of many possibilities and should be treated as the exemplary case elaborated and tested at the Silesian University of Technology in Gliwice.
