HIGH Reliability and Efficiency
High Permissible Torque
The permissible torque is twice that of conventional models
Increase in the strength of the gear raises the maximum permissible torque to twice the torque when compared with conventional models. A torque range that was unavailable can now be used.
High Strength
Permissible load is up to twice as high in comparison to that of conventional models
The strength of the permissible radial load and the permissible axial load is twice that of the conventional model.
Conventional model 4GN-K
Permissible radial load
200 N
Permissible axial load
50 N
KII Series 4GN-K
Permissible radial load
450 N
Permissible axial load
100 N
Long Life
The rated life is twice that of the conventional model
The large bore bearing used for this model extends the gearhead's rated life to 10,000 hours, which is twice that of the conventional model. This reduces the maintenance work for the device.
Rated life hours: Definition determined by China Motor. For details, contact China Motor.
Comparison of the rated life hours
Silent
Reduced gear contact noise by 50%
Noises from motor/gearhead contact have been reduced by 6 dB compared with the conventional standard motor.
This simply means the noises have been halved.
Comparison of the noise level in the 80 mm frame size type
The optimal magnetic design and dedicated parts have dramatically reduced losses, achieving high efficiency. Compared with the conventional 90 W model under the same conditions, the new one has lower power consumption, contributing to a labor-saving device since the reliability has been aslo increased.
Low heat generation and low vibration
With less heat generation and vibration of the motor, achieved by reduced losses, the reliability of the device has been significantly increased.
Comparison with conventional model
High Efficiency in compliance with IEC 60034-2-1
A motor efficiency of 77.8% (IE4, classification) and 73.3% (IE3 classification) is achieved with optimal magnet
design and specialized parts. Loss is greatly reduced, the motor's output is increased, and it is fanless.
Environmental Resistance
Fan-less structure
Reduction in loss has reduced the heat generation in the motor. Therefore, the KII Series’s singlephase 220/230 VAC 50 Hz type and the KIIS Series do not require the cooling fan that was installed in the conventional models of 60 W
or higher, resolving the problem of raising dust.
Water resistance specification in compliance with IEC 60034-5
The sealing structure of the motor, gearhead, and terminal box has been strengthened. The terminal box type conforms to the IP66 rating degree of protection.
- Material Case and terminal box: Aluminum
- Output shaft: S45C
- Screw: Stainless steel (Exposed part only)
- Surface treatment Case and terminal box: Painted (Except the installation surface)
Best For Combination With An Inverter (KIIS Series only)
Variable speed control
By combining with an inverter, you can control the speed in a wide range from the low speed at 3 Hz to the high speed up to 120 Hz. Even at a low speed, high torque is produced. In addition, less variation under loads enables more stable speed control.
About use with an inverter of other manufacturers
For easy use of an inverter, we provide, for your reference, the "Speed - Torque characteristics" and "Parameter settings for the inverter" when this product is combined with an inverter of another manufacturer.
UNIQUE User Friendly Design
The overall length is reduced by the removal of the decimal gearhead
The gearhead lineup offers a wide range of gear ratios from low gear ratios up to a maximum of 1:360. For the high gear ratios over
1:180, the decimal gearhead was previously required. Now, only one gearhead is required, achieving a saving of space.
Output Axis Tapping
For motors with 25 W output power or higher, tapping has been applied to the output shaft end. This prevents the pulley and other transmission parts from coming off.
Increase Installation Accuracy
The installation surface and pilot of the gearhead are polished. The gearhead can be installed into the device more accurately.
Uses a hypoid gear with built-In Oil Seal
Oil seal is installed in the final stage of the output shaft. This prevents grease from leaking. Furthermore, 40 W and higher
motors use a special oil seal with high sealing performance. This provides highly reliable measures against grease leakage.
• Hypoid gear used on first step of reducer
• High-strength helical gear installed on last step to increase strength
• Shaft/gear where carburizing treatment was applied
• Oil seal
• Grease leak measures implemented
• Special oil seal used to enhance seal performance
Combination Type
Pre-assembled gearhead
The combination type comes with a motor and a gearhead pre-assembled. This type makes the installation into the
device easy, and you no longer have to worry about giving damage to the shaft, which may cause abnormal noise.
The combination type comes with the motor and gearhead pre-assembled with dedicated screws. Motors and gearheads are also available individually for maintenance.
Slim Terminal Box
Improvement in workability
A slim terminal box is used to make wiring work easier. The box is slimmer than conventional products. The cable outlet
can be changed by 90 degrees to four different directions. The slim terminal box type conforms to the IP66 rating degree
of protection. (Except the installation surface of the round shaft type)
