..., 2006). The most obvious advantage of a linear motor is that it develops a direct linear motion without the need of gears or mechanical rotary-to-linear transformation. Linear motors can be classified as follows: induction motors, synchronous motors, DC motors. Among these, the LIM has many excellent...

...N. Bianchi; A. Canova; G. Gruosso; M. Repetto; F. Tonel The optimisation of a tubular linear motor with interior permanent magnets is described. For a rapid design the whole process is divided in three parts: an analytical approach for the a preliminary investigation, a parametric analysis by means...
