小型ダイレクトドライブモータのマイクロテック・ラボラトリー

During wavelength inspection using laser light, it is possible to extract any desired wavelength by passing the laser light through the motor shaft and attaching a wavelength plate to the motor end face. However, when the inner wall surface of the shaft is silver, it reflects the laser light, causing difficulties in evaluation.

Therefore, by changing the motor shaft to aluminum material and applying black anodized treatment to the surface, it is possible to suppress the reflection of laser light.

※compared to the standard SUS material, there is a reduction in load-bearing capacity.
