I'm confused, you called in a linear induction motor, but the dude said it used magnets and was a synchronous motor. Induction motors don't have permanent magnets nor are they synchronous, so like, which is it?,(reply>), they would be magnetic linear actuators,(reply>), LIMs could potentially be used, and might well be cheaper for the shaft; but this company just aren't.<br><br>FYI Tesla uses induction motors in his cars, they can be precisely computer controlled just fine. They are a bit less efficient at low speeds, but not terribly so, particularly if they have a thick secondary.,(reply>), Yeah, pretty sure it's the synchronous one. Induction motors (and linear actuators) have slip, can't be controlled for precise positioning and don't work well at low speeds,(reply>), Tom messed it up, pretty sure.
