High Performance AC Gear Motors
High Permissible Torque
The maximum permissible torque has doubled compared to conventional products, thanks to increased gear strength* which provides a torque range that exceeds anything previously offered. Downsizing is also possible by switching the motors used in the past to the KII Series. If a small motor is selected, power consumption can be suppressed and costs can be reduced.
*Triple in 40 W products
Downsizing is possible with the same output torque.
Geared motors with twice the permissible torque compared to conventional geared motors and now with higher gear ratios.
High Strength
Permissible overhung load and permissible thrust load have doubled compared to conventional products*. This has been made possible by increasing the case rigidity, adding larger diameter bearings and improved gear strength through heat treatment.
*The same in some products.
Permissible overhung load and permissible thrust load have doubled compared to conventional products. (40 W vs. 25 W comparison).
Long Life
The gearhead ball bearing diameter has increased, resulting in doubling the life of the gearhead (10,000 hours compared to the rated life of 5,000 hours for conventional gearheads). Performing maintenance has decreased as a result of the longer life.
The rated life has doubled compared to conventional products.
Quiet
The motor and gearhead noise (meshing sound) has decreased by approximately 6 dB compared to conventional motors. Put into perspective, the noise level has decreased by 50%.
The gearhead noise has been decreased by 6 dB compared to conventional products.
Combination Type
The motor and gearhead come pre-assembled and ready to install. Concerns of damage resulting from improper gearhead installation leading to abnormal noise in the shaft are eliminated.
Easy installation thanks to the pre-assembled motor and gearhead.
High Gear Ratio
Decimal gearheads were once required for gear ratios above 1:180. Now a single gearhead is available (up to 1:360), saving space and reducing components and costs.
No decimal gearhead is required, allowing the total length to be shortened.
Tap Output Shaft
An end tap has been integrated into the tip of the output shaft of gearheads, with a rated output power of 25 W (1/30 HP) and higher. The tap can be used to prevent pulleys and other transmission mechanisms from slipping.
Slim Body Terminal Box Type (IP Rating)
This new shape of terminal box is designed to make wiring the terminal block easier. It has a slim body, with a cable outlet that can be rotated in 90° increments for 4 possible directions.
IP66 Compliant Drip-proof Specification
The seal structure for the motor, gearhead and terminal box components has been strengthened. The terminal box type is compliant with the IP66 degree of protection.
Reversible AC Motors
Ideal for Instantaneous Bi-Directional Operation
The motor has a built-in friction brake mechanism (friction brake) at its rear. This is ideal for the applications below.
- To repeatedly use the instantaneous bi-directional operation
- To reduce overrun
The new brake shoe with new structure experiences less aging deterioration than before.
Electromagnetic Brake Type
- 6 W (1/125 HP)
- 15 W (1/50 HP)
- 25 W (1/30 HP)
- 40 W (1/12 HP)
- 60 W (1/12 HP)
- 90 W (1/8 HP)
These motors have a "power off" activated type electromagnetic brake to hold the load in position when the power is cut off.
Ideal for Applications Required Load Holding
This configuration is ideal for vertical applications where the load must be held.
Power Off Activated Type Electromagnetic Brake Equipped
An AC power off activated type electromagnetic brake is equipped. When the power source is turned OFF, the motor stops instantaneously and holds the load.
Brake Pack
The SB50W provides instantaneous stop, bi-directional operation and electromagnetic brake control functions integrated into one unit. This brake pack can sense when the thermal protector is opened, ensuring the safety of your equipment. For greater convenience, a function has been added to reset alarms using an external signal.
Capacitor Mounting Bracket
This capacitor mounting plate allows you to attach an AC motor or Fan motor’s capacitor on a DIN rail. You can attach or detach in on a DIN rail with a one screw. There is no need for a separate end plate or additional components.
Flexible Couplings
These products are clamp type couplings used to connect a motor or gearhead shaft to the shaft of the equipment.
Mounting Bracket
This is an aluminum die cast mounting bracket for geared motors.
Long, horizontal holes make it easy to make fine adjustments during installation.
CR Circuit for Surge Suppression
This is used to protect the contacts of the relay or switch used in the bi-directional circuit or the instantaneous stop circuit of a motor.
