Linear DC Motors (LDM), used in office automation equipments (OA) such as line printers and image scanners, are required to be with high acceleration and fast-response. Under the condition of limited power supply capacity and an outside dimension, we investigate the structure of LDM to make the acceleration rise most quickly by using finite element method. In this paper, we examine the single-supported and double-supported LDMs. Target of acceleration, direct current and response time of acceleration are 490 m/s2, below10 A and 0.15 ms. As a result, double-supported LDM's maximum acceleration is 655 m/s2 and response time of acceleration is 0.36 ms, so the target is not achieved, but comparing to single-supported LDM, response time of acceleration is less than 0.59 ms.
