The target audience consists of end-users of commercially-available products, as well as those interested in designing their own custom-made linear motors. The course begins by categorizing different types of linear motors and reviews the underlying theory behind force generation in them. We continue with an in-depth description of coil winding and magnet array design, and a review of a typical motor specification sheet. We conclude the linear motor portion of the tutorial with guidelines for applying linear motors. This includes a comparison of screw-based and direct-drive systems, cogging, force ripple, stray field containment, eddy-current reduction, and cooling. The second part of the tutorial covers power electronics. We review three-phase power calculation and circuit analysis, commutation, amplifier design, and current-loop tuning. Finally, we look at the implications of embedded microprocessors in next-generation digital amplifiers.
