2.4 Comparison of Geared Servo Motors
POINT
Geared servo motors are not included in the HG-MR, HG-RR series.
2.4.1 Comparison of actual reduction ratios for geared servo motors
Because the actual reduction ratio for some models is different when replacing HC-KFS or MFS_G1 with
HG-KR_G1, it is required that an electronic gear be set up.
For general industrial machines: HC-KFS, HC-MFS_G1

2.4.2 Comparison of reducer efficiency of geared servo motors
The gear reducer efficiency is different when HC-KFS or HC-MFS_G2 is replaced with HG-KR_G7, or HC-
SFS or HC-RFS_G2 is replaced with HG-SR_G7.
Model
Reducer efficiency (Note) Substitute model
Reducer efficiency (Note)
HC-KFS_G2
60 to 80%
HG-KR_G7
50 W (reducer model 14A):
12% (reduction ratio 1/5), 22 to 34% (reduction ratio
1/11 to 1/45)
50 W (reducer model 11B)/100 W/400 W/750 W:
48 to 84%
HC-MFS_G2
HC-SFS_G2
80 to 90%
HG-SR_G7
77 to 92%
HC-RFS_G2
Note. The reducer efficiency differs depending on the reduction ratio. Also, it changes depending on the operating conditions
such as the output torque, speed and rotation, temperature, etc. The numerical value in the table is a typical value in the
rated torque, rated speed and rotation and typical temperature, and not a guaranteed value.
