Main Question or Discussion Point
we were learning about electrical motors in class the other day and my teacher mentioned linear electric motors, which from what he said are basically standard motors 'unravelled'. i was wondering why, if this is the case, you would ever use a standard motor when linear motion was required? why use a 'rotational' motor in combination with camshaft (or equivalent) to convert the rotational motion to linear? if you wanted to change from a rotational motor to a linear motor (when linear motion is required) is it as simple as simply swapping them out and changing the 'drive' shafts? thanks.
