Servo motors are being used in more and more varied linear applications, such as shaping surfboards and building auto tires. So there's a growing pool of true believers in the capability of direct-drive linear motors compared with more traditional approaches of translating rotary motor motion to linear or using mechanical means. Others think that's baloney. Read "Linear Motion Moves Up and Out" to find out what we learned, and then tell us if and why you picked a side.
