Title: Scale structure in linear pulse motor
Inventor: NAKAGAWA HIROSHI
IPC: H02K41/03
Filed: 1987-02-23
Abstract: PURPOSE:To improve the operability of a linear pulse motor by disposing a thin plate which covers the teeth of a secondary scale to prevent the teeth from separating or deforming. CONSTITUTION:A thin plate 101 is bonded with an adhesive (c) to the upper surface of a teeth 16a bonded with the adhesive (c) onto a scale base 16b. The plate 101 uses a plate of an amorphous alloy having 0.01-0.15mm. Thus, even if metal pieces, dusts are dropped to be adhered onto the scale, since the scale face with the teeth 16a is flat, the pieces and the dusts are caught by the uneven surface of the teeth 16a entrapped into the gap between a movable element and the scale, thereby damaging no teeth 16a. Since the teeth 16a do not directly contact the scale at the time of attaching or detaching the scale, the operating teeth 16a are neither separating nor deforming, thereby improving the operability.
