Precautions for Handling Geared Motors

Turning by output shaft

Do not turn a geared motor by its output shaft when, for example, arranging its position so as to install it. 
The gearhead will become a speed-increasing mechanism, which will have harmful effects, damaging the gears and other internal parts; and the motor will turn into an electrical generator.

Installed position

For the installed position we recommend a horizontal position --the position used in our company's shipping inspection.
With other positions, grease might leak onto the geared motor, the load might change, and the motor's properties might change from those in the horizontal position. Please be careful.

Additional processing

Various kinds of processing are possible for the output shaft.
※However, it is necessary to be careful when processing, as the load,an impact, powder from cutting, etc., during processing can damage the product.


Install the screws after first checking the taps and tap depth against the dimensions entered on the exterior drawing.
※If, when a geared motor is installed, the screws are too long or their tightening torque is too great, the motor's internal mechanical parts could become deformed or break or the screws could become deformed, resulting in a breakdown. If the tightening torque is too weak, on the other hand, it could cause the motor to rattle or fall off.

Installation of geared motor on output shaft

Please be careful with regard to applying adhesive.
※It is necessary to be careful that the adhesive does not spread along the shaft and flow into the bearing, etc. Moreover, do not use a silicon adhesive or other volatile adhesive, as it could harmfully affect themotor's interior. In addition, avoid press fitting, as it could deform or damage the motor's internal mechanism.

Handling the motor terminal

Please conduct the welding work in a short time.. (Recommendation: With the soldering iron tip at a temperatureof 340 - 400℃, within 2 seconds.)
※Applying more heat than is necessary to the terminal can melt the motor's parts or otherwise harm its internal structure. Moreover, applying excessive force to the terminal area can put stress on themotor's interior and damage it.


Grease is applied to the sliding areas of the gears, etc.
※Be careful about using the product in a special environment. Due to the structure of geared motors, the grease could ooze out to the exterior.

Temperature range for use

Geared motors should be used at a temperature of -10~60℃. The figures stated in the catalog specifications are based on use atordinary room temperature (approximately 20~25℃.
※If a geared motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to functionnormally and the motor will become unable to start. Depending on the temperature conditions, it may be possible to deal with them by changing the grease or the motor's parts. Please feel free to consult with us about this.

emperature range for storage

Geared motors should be stored at a temperature of -15~65℃.
※In case of storage outside this range, the grease on the gearhead area will become unable to function normally and the motor will becomeunable to start.

Relative humidity range

Geared motors should be used in 20 - 85% relative humidity (no dew condensation).
※In a humid environment, the metal parts might rust, causing abnormalities. 
Therefore, please be careful about use in such an environment.

Long-term storage

Do not store a geared motor in an environment where there are materials that can generate corrosive gas, toxic gas, etc., or where the temperature is excessively high or low or there is much humidity. Please be especially careful with regard to storage for lengthy periods such as 2 years or more.


The longevity of geared motors is greatly affected by the load conditions, the mode of operation, the environment of use, etc. Therefore, it is necessary to check the conditions under which the product will actually be used. The following conditions will have a negative effect on longevity. 
Please consult with us should any of them apply. 
■Use with a load that exceeds the rated torque   ■Frequent starting 
■Momentary reversals of turning direction            ■Impact loads 
■Long-term continuous operation    ■Forced turning using the output shaft   
■Use in which the permitted overhang load or the permitted thrust load is exceeded . 
■A pulse drive, e.g., a short break, counter electromotive force, PWM Control 
■Use of a voltage that is nonstandard as regards the rated voltage
■Use outside the prescribed temperature or relative-humidity range, or in a special environment
■Please consult with us about these or any other conditions of use that may apply, so that we can be sure that you select the most appropriate model.
