Contributing to a more compact multi-axis actuator NSK Ltd. (NSK; Headquarters: Tokyo, Japan; President and CEO: Toshihiro Uchiyama) today announced that it has developed a dual-axis integrated motor that is capable of two independent rotary motion outputs. This product was developed to simplify actuator construction and make it more compact. By applying NSK Megatorque Motor™ technology, a 2.62 million count/rotation high resolving power is achieved. By integrating two axes, wiring for each cable type is simplified, resulting in an advanced actuator and contributing to reduced maintenance. NSK will exhibit this new product at the International Robot Exhibition 2015, to be held at Tokyo Big Sight (Koto-ku, Tokyo) from Wednesday, December 2 to Saturday, December 5. NSK will search for potential practical applications for this product such as in the robotics market. Development Background The shift to compact, multi-axis products in production facilities requires more compact, versatile actuators with improvements to their maintenance cycles. To achieve two independent rotary motion outputs on conventional products, it was necessary to use two motors, requiring a significant amount of space. To create a more compact, versatile actuator, NSK developed a dual-axis integrated motor that is capable of two independent rotary motion outputs. Also, because the motors are maintenance-free for long periods, it contributes to extended periods of time between maintenance cycles. NSK continues to contribute to the development of environmentally friendly products in the industrial machinery field.

Product Features The original inside/outside motor stator integrated design makes the product more compact (30% reduced volume in NSK comparison) Simplified wiring for each cable type A hollow hole is placed in the center of the motor for simplified wiring and tubing Enables installation in any direction Uses NSK Megatorque Motor™ technology Achieves 2.62 million count/rotation (angle: 0.5 sec) high resolving power Built-in absolute position sensor 10s-1 (600min-1) high-speed rotation Long-term maintenance-free operation via the direct drive
