Note: 1. The allowable output speed is affected by duty cycle, load, and ambient temperature. When the allowable output speed is above NS1, please consult our company about the precautions. 2. Calculate the input capacity (kW) by the following formula.

Input capacity (kW)=2π*N*T/60*η/100*10*10*10

N: output speed (RPM) T: output torque (nm) η =  75: reducer efficiency (%)

The input capacity is the reference value. 3. When using the reducer at a low temperature, the no-load running torque will increase, so please pay attention when selecting the motor. (refer to low-temperature characteristics)

4. The allowable torque will vary according to the thrust load. Please confirm by the allowable moment line diagram. 5. For moment stiffness and torsion stiffness, please refer to the inclination angle and torsion angle calculation. 6. Rated torque refers to the torque value reflecting the rated life at rated output speed, not the data showing the upper limit of load. Please refer to the glossary (p.81) and product selection flow chart (p.82). 7. The above specifications are obtained according to the company's evaluation method. Please confirm that the product meets the use conditions of carrying real aircraft before use. 8. When the radial load is within dimension B, please use it within the allowable radial load range.
