Advantages of Increased Permissible Radial Load
Permissible radial load has been increased for the mini connector type.
High-Resolution Type
This motor has a basic step angle of 0.9°. This results in a greater positioning accuracy. In addition, the displacement angle when external force is applied to the shaft is smaller than that of the standard type.
Comparison of Displacement Angles Due to Frictional Load (Reference values)
For a friction load of 0.3 N·m
Flat Type
This flat stepper motor can be installed in small spaces. It is useful in various situations such as index tables and robot joints.

| Mass | 0.11 kg | 0.2 kg |
| Maximum Holding Torque | 0.1 N·m | 0.18 N·m |
With Harmonic Gearheads
Combined with harmonic gearheads, high-torque, large-inertia drive is possible. Since the load can be mounted directly on the rotating surface, it can be easily accommodated in the narrow space of a robot joint.
| Gear Ratio | 100 |

| Maximum Holding Torque | 2.4 N·m |
| Mass | 0.32 kg |
| Motor Length | 17 mm |

Geared Type
By using the geared type, the advantages of deceleration, high torque, and high resolution can be obtained. Torque can be increased without changing the frame size even when motor installation space is limited.
