Output shaft rotating direction
Servo motor shaft and reduction gear output
shaft rotate in the same direction. For the
HA-FF053G1 1/30 and HA-FF3G1 1/30, how-
ever, the servo motor shaft and reduction gear
output shaft rotate in the opposite directions.
Servo motor shaft and reduction gear
output-shaft rotate in the same direction.
With electromagnetic brake Available
Backlash (Note 1) 40 minutes to 1.5 Within 3 minutes
(Note 2) Permissible load inertia
moment ratio (when converting
into the servo motor shaft)
5 times or less
Permissible speed
(at servo motor shaft)
3000 r/min
Reduction gear efficiency (Note 4) 73 to 85% 80 to 90%
Note 1. The above values are typical values and not guaranteed values.
2. If the above indicated value is exceeded, please consult us.
3. Maintenance-free.
4. The reduction gear efficiency differs depending on the reduction ratio.
Also, it changes depending on the use 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.
The actual reduction ratios of the servo motors with reduction gears designed for general industrial
machines are as listed below.
