Geared servo motor

When using an oil-lubricated geared servo motor, remove the oil when transporting and mounting the servo
motor. If the geared servo motor is tipped over while filled with oil, oil leakage may occur.
Do not attach a gear reducer removed from a geared servo motor to a rotary servo motor that originally does
not have a gear reducer. If the geared servo motor being used requires repair, contact your local sales office.
The geared servo motors are for general industrial machine and for high precision applications.
Some geared rotary servo motors also have an electromagnetic brake.

*1 If the permissible load to motor inertia ratio exceeds the indicated values, contact your local sales office.
*2 The gear reducer efficiency varies depending on the reduction ratio. The gear reducer efficiency also varies depending on the operating
conditions such as output torque, speed, and temperature. The values in the table are the representative values at the rated torque,
rated speed, and the room temperature, and are not guaranteed values.
*3 The unit of backlash is calculated as follows: 1 arc minute = 0.0167 °
*4 The maximum torque of the geared servo motor does not increase even if in combination with a servo amplifier with a larger capacity.
