Direct drive motors are finding their way into telescope drive designs and have many advantages over more traditionally used friction and rack/pinion drives. They are implemented as curved linear motors custom made to the actual diameter required by the telescope design. Custom design is by definition a costly process and this paper discusses the possibility to use standard straight linear segments to approximate the curvature. Detailed analysis is given concerning differences in the electro-magnetic properties compared to a custom design motor.
