Selection
1. Package ：Select package type: A, B, C, or X type
C type: with tough gear from your application.
2. Determine the service factor
From the Load Categories by Machine Type (table 2), a mixer (kneader) has a load characteristic of M, which gives sf = 1.25 from the service factor table (table 1).
3. Determine compensation torque
Use the service factor and load torque to obtain the compensation torque.
Correction torque = 605N・m × 1.25 ≒ 726N・m
4. Determination of reduction ratio
Use the motor speed and output speed to obtain the reduction ratio.
Reduction ratio = 1450r/min ÷ 1.45r/min ≒ 1000
5. Determine a size
C Type ：From the Characteristics table, select the size that satisfies the compensation torque and reduction ratio.
Size ：SWGM100HC - 1/1000 Motor ：0.2kW
6. Check shaft load
Check that the radial load on the output shaft is within the allowable load.
Radial load ：500N < allowable radial load = 6478 N and is acceptable
7. Determine size and model
From vertical mount (V type), hollow output shaft (H), your selection is Model: SWGM100HCV1000RF(LF)020.
