2.Gear motor using the matters needing attention
Gear motor using the matters needing attention
|
The rotation of the output shaft |
Please don't when installing parts in order to adjust the position and direction from the output shaft rotary gear motor。
※Gear head will be a growth mechanism, cause internal damage, such as gear motors as generators。 |
Installation position |
Standard installation position is the same as the quality control in the horizontal position
。
※Please pay attention to. Used in other direction position, is likely to cause the gear motor oil leakage, load changes, that change with the characteristics of the horizontal direction changes. |
Processing
|
A wide variety of machining can be imposed output shaft
。
※Carry on the processing, the processing load, shock, cutting powder could cause the damage of the products
。 |
Screw
|
Before install the screw, please confirm the length label form and the appearance figure size.
Does installing a gear motor, screw is too long, the bolt is too metropolitan cause internal mechanism parts deformation and breakage, deformation of the screw itself can lead to accidents. In addition, when the bolt is too weak, may be the cause of instability or fall off. When used please note.
|
The installation of the output shaft
|
Please be careful with uf agent
。
※Please be careful with, do not make the agent of uf resin by output shaft into the shaft. Especially volatile silicon adhesive glue, may cause harmful effect on the motor internal, please avoid to use. In addition, please avoid excessive pressure, deformation and damage in case of internal institution.
|
The motor terminals
|
Welding operation in a short period of time, please. (recommended: the temperature of the welding head in 340-400 degrees, 2 seconds)
※Terminal overheating will cause the motor parts of dissolved and produce adverse effects of internal structure. In addition, impose pressure on terminal part, can add the motor internal burden, cause internal damage of the motor
。 |
Lubricating oil
|
Apply sliding part of the gear
。
※Used in special circumstances, please be careful when using. According to motor structure characteristic, may flow to the outside
。 |
Using the temperature range
|
Please - have a range of 10 ℃ ~ + 60 ℃. The value recorded in the directory for the values in the room temperature 20 ℃ to 25 ℃
。
※Outside the specified range of temperature, when using the gear head of lubricating oil will be unable to work properly, the motor cannot be started. According to the different temperature conditions, changes of lubricating oil and motor parts can make the motor in the temperature range after use. If necessary, please inquire.
|
Save the temperature range
|
Please save in 15 ℃ ~ + 65 ℃.
※Save in the temperature range, head gear lubricating oil yield function does not work, the motor cannot be started
。 |
Relative humidity range |
Please in humidity 20% ~ 20% RH, without condensation within the scope of use.
※Humid environment, due to the rusty metal parts can cause abnormal function, please carefully use
。 |
Safekeeping
|
Please avoid stored in containing corrosive gas, toxic gas, high temperature, low temperature, high humidity environment. Especially when more than 2 years of long-term preservation, please special care.
|
The service life of the
|
Life of the gear motor, due to the load condition, action mode, using the environment is very different for the different. Please confirm with actual product fully
。
Under the condition that affects the service life of the reason, please inquire with us.
■The use of beyond the rated torque load
■Frequent start
■Is the inverse moment reversal of direction
■Impact loading
■Long time continuous operation
■Mandatory rotation output shaft
■Beyond outstanding suspension allowable load heavy, beyond the permissible use of thrust load
■Braking, reverse current, PWM pulse driving braking and so on
■Use standard rated voltage specifications
■Beyond the temperature range, relative humidity range, or used in special environment。
■Other USES, the environment, when using, please negotiate with us, we will select suitable models according to need. |

3.Why choose dc motor
？
any applications require large starting torque. The dc motor is the slow down of its own features, high torque feature. This allows it to deal with the application of large starting torque, and can easily absorb the load mutation. The motor speed can be adjusted to adapt to the load. Moreover, the dc motor is an ideal solution for miniaturization. Designers tend to consider dc motor, it is just because of the dc motor's efficiency is higher than other types of motor

4.How to choose the SGMADA various types of motor
According to the requirement of the output power choose motor type, in accordance with the requirements of speed, choose dc motors and gear motors, speed: 1000 to 5000 RPM, dc motor, speed, less than 500 RPM, gear motor, according to the required torque and maximum working load to select a gear box.
