Specifications
| Model | Rated torque ［N・m］ | Misalignment | Max. rotation speed ［min-1］ | Torsional stiffness ［N・m/rad］ | Moment of inertia ［kg・m2］ | Mass ［kg］ | |
|---|---|---|---|---|---|---|---|
| Parallel ［mm］ | Angular ［°］ | ||||||
| CPU-26-A | 2.2 | 0.3 | 4 | 4000 | 600 | 3.57×10-6 | 0.04 |
| CPU-36-A | 10 | 0.4 | 4 | 3500 | 1350 | 1.64×10-5 | 0.09 |
| CPU-46-A | 25 | 0.5 | 4 | 3000 | 1650 | 5.33×10-5 | 0.19 |
*Max. rotation speed does not take into account dynamic balance.
*The moment of Inertia and mass are measured for the maximum bore diameter.
