Oriental Motor, which has set the standard for AC motors, listened and has sought out the next generation in AC motors with the KII Series reversible or electromagnetic brake motors. The KII Series also offers the high strength Parallel Shaft type gears that maximize motor performance with simple wiring and flexible mounting options. The KII Series is available from 6 W (1/125 HP) up to 90 W (1/8 HP) with either Imperial or Metric standard output shafts.

*Torque and Speed vary based on input voltage and frequency, please review product specifications for details.
The magnetic balance for each input voltage has been re-examined and the motors have been specifically designed to optiize their characteristics.
Designing specifically for each voltage not only improves efficiency, but also contributes to equipment reliability by reducing heat and vibration generated by the motor.
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.
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).
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.
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.
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.
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.
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.
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.
The motor has a built-in friction brake mechanism (friction brake) at its rear. This is ideal for the applications below.
The new brake shoe with new structure experiences less aging deterioration than before.
These motors have a "power off" activated type electromagnetic brake to hold the load in position when the power is cut off.
This configuration is ideal for vertical applications where the load must be held.
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.
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.
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.
Lead wire set for AC motor capacitors.
These products are clamp type couplings used to connect a motor or gearhead shaft to the shaft of the equipment.
This is an aluminum die cast mounting bracket for geared motors.
Long, horizontal holes make it easy to make fine adjustments during installation.
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.
