12. SERVO MOTOR
12.7.4 Geared servo motors
CAUTION
Do not disassemble, repair, or modify the geared servo motor.
Do not remove the gear reducer from the geared servo motor to install it to a non-
geared servo motor. To repair the geared servo motor, contact your local sales
office.
Geared servo motors are available for general industrial machines and high precision applications.
Servo motors with an electromagnetic brake are also available.
(1) For general industrial machines (G1)
(a) Reduction ratio
The following table indicates the reduction ratios and actual reduction ratios of the geared servo motor
for general industrial machines.
(b) Specifications

(Note 3)
60 minutes or less at gear reducer output shaft
Permissible load to motor
inertia ratio
(converted into the servo
motor shaft)
(Note 1)
50W/100W: 5 times or less
200W/400W: 7 times or less
Gear reducer efficiency
(Note 2)
40% to 85%
Note 1. If the above indicated value is exceeded, please contact your local sales office.
2. The gear reducer efficiency differs depending on the reduction ratio. Also, the gear reducer
efficiency 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.
3. The backlash can be converted. 1 min = 0.0167˚
