Geared servo motor
Precautions
Mount the geared rotary servo motor in the specified mounting direction.
Not doing so will cause oil leakage which may lead to a fire and malfunction.
For handling, recommended grease/lubricating oil, positions of oil ports, maintenance, and inspection of the
gear reducer, refer to the instruction manual "Cyclo
the product and to the manufacturer's website.
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 servo motor which originally does not
have a gear reducer. If the geared servo motor being used requires repair, contact your local sales office.
The geared rotary servo motors are for general industrial machine and for high precision applications.
Some geared rotary servo motors also have an electromagnetic brake.

Gear reducer efficiency
*1 For grease-lubricated geared servo motors, grease is filled from the factory.
*2 If the permissible load to motor inertia ratio exceeds the indicated values, contact your local sales office.
*3 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.
*4 This is a design value and not a guaranteed value.
*5 The unit of backlash is calculated as follows: 1 arc minute = 0.0167 °
*6 The torque characteristics of the HK-ST152(4) is the specifications calculated by derating the HK-ST172(4)W with the output ratio (rated
torque: 7.2 N•m) . The moment of inertia and characteristics of electromagnetic brake are the same as those of the HK-ST172(4)W.
*7 The torque of the geared servo motor does not increase even if in combination with a servo amplifier with a larger capacity.
