加速度および推力特性に着目した可動磁石形リニア直流モータの検討 Investigation of Moving-Magnet Linear DC Motor Focused on Acceleration and Thrust Characteristics
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, the structure of LDM to make the acceleration rise most quickly is investigated by using finite element method. The target of acceleration, direct current and response time of acceleration are 490 m/s<sup>2</sup>, below10 A and 0.15 ms. As a result, maximum acceleration is 516 m/s<sup>2</sup> and response time of acceleration is 0.125 ms, so the target is achieved.
