发明名称 SEMICONDUCTOR LINEAR MOTOR
摘要 PURPOSE:To simplify the construction and to reduce the cost of a semiconductor linear motor by employing an encoder, detecting the origin of the encoder, and flowing a current of the direction adapted for the adequate position by dividing the frequency of a pulse signal. CONSTITUTION:A movable element 3 is formed of a U-shaped sectional member, and linearly moved along guide rails provided at a stator 2. A 4-pole field magnet is secured to the lower surface of a body 3a of the element 3, and planely opposed to a printed board 6 of a stator armature 5. A linear encoder 8 having a linear scale 9 is mounted. The prescribed number of pulses from the original position of the encoder 8 is counted, and a current of the prescribed direction is flowed to the armature coil 5 on the basis of the counted number, thereby controlling the movement of the element 3.
