High Accuracy
Due to non-backlash, the output shaft moves and stops with very high accuracy relative to the motor command position.
It is suitable for applications and mechanisms that require stopping at an exact amount or position, such as dispensing and transferring in the medical field.
- Lost Motion [arcmin]:
1.5 (0.025°) or less (±2 mN·m) - Angular Transmission Accuracy [arcmin]:
10 (0.167°) or less
Large Inertia Drive
Gear ratios of 30, 50, and 100 are available.
The lineup of high gear ratios makes it possible to drive fine movements such as precision stages, and large inertial bodies.
| Gear Ratio | Basic Step Angle |
|---|---|
| 30 | 0.06° |
| 50 | 0.036° |
| 100 | 0.018° |
Flat Torque Characteristics up to High Speeds Standard Type
It has flat torque characteristics up to high speeds.
Suitable for applications such as long positioning distances for ball screw mechanisms and high-speed motor operation.
