YAMAHA N type Nut rotation type model Pricing & Product Details

Yamaha's N type Nut rotation type model is designed to provide high-speed transfer with a stroke ranging from 250 to 2500mm. It can achieve a maximum speed of 1200mm/sec and has a repeatability of +/-0.01mm. With a maximum payload capacity of 50 to 80kg, this model is suitable for various applications.

The N type model uses a 4-row circular arc groove type 2-point contact guide that is resistant to large moment loads, ensuring excellent reliability and durability. Two guide frames are laid out on the high rigidity aluminum extruded material frame for the F type, N type, and B type, while the F8 series uses a newly developed module guide to reduce the cross-sectional area by 70%. Additionally, Yamaha uses a resolver for the position detector, which provides excellent environment resistance and has a long service life, reducing maintenance costs.

The N type Nut rotation type model offers a high-speed transfer even with a long stroke, as the ball screw nut is linked to the hollow motor, and the ball screw does not rotate, thus not restricting the critical speed. This model also allows for a double carrier to be arranged coaxially, resulting in space saving and cost reduction when compared to using two single axis robots. Yamaha offers custom specifications and supports various applications, such as the addition of a free slider or wide slider, specified stroke, lead beyond catalog, and origin non-motor specifications.

In summary, Yamaha's N type Nut rotation type model is suitable for applications that require high-speed transfer, a long stroke, and a high payload capacity. Its features, such as the 4-row circular arc groove type 2-point contact guide and resolver position detector, provide excellent reliability and durability, reducing maintenance costs for customers.

●F8 series

The F8 series uses a newly developed module guide to greatly reduce the crosssectional area (70 % when compared to F10). The rail is laid out in the full width of the frame to ensure the high rigidity even with compact design. Of course, this series also uses the 4-row circular arc groove type 2-point contact guide.

Note 2. Except for F8 series/F10/B10.

Resolver with excellent environment resistance is used for the position detector.

A resolver is used for the position detector. The resolver has a simple and rigid structure without using electronic components and optical elements. Detection problems due to electronic component breakdown, dew condensation on or oil sticking to the disk that may occur in optical encoders do not occur in the resolver. The resolver provides excellent durability. Additionally, as the absolute specifications and incremental specifications use the same mechanical specifications and common controller, desired specifications can be selected only by setting parameters. Furthermore, even when the absolute battery is consumed completely, the robot can still operate as the incremental specifications. So, even if a trouble occurs, the line stop is not needed to ensure the safe production line. Furthermore, the backup circuit has been completely renovated and now has a backup period of one year in the non-energizing state.

Long service life greatly reduces the maintenance cost.

As the acceleration is determined by the weight parameter, the service life can be assured when the weight and position of center of gravity are known.

YAMAHA's robot uses high rigidity ball screw or guide, it provides excellent durability. This greatly contributes to reduction of the customer's maintenance cost.

Controllers suitable for applications are prepared.

In addition to the robot program operation and pulse train control, a positioner that is operated by specifying a point number was added to the product lineup. Additionally, multi specifications that control multiple robots using one controller are also supported. You can select an optimal controller suitable for your application.

Various custom specifications are supported.

YAMAHA supports custom orders flexibility to meet the customers' various needs.

N type structure

In this structure, movement　is via a nut that rotates while　clamped to a screw shaft, the　ball screw nut is linked to the hollow motor.

A high-speed transfer is possible even with a long stroke.

As the ball screw does not rotate, the critical speed is not restricted.
This ensures a high-speed transfer even with a long stroke.

Double carrier available as a standard

Two carriers can be arranged coaxially by utilizing the features of the nut rotation type.
Space saving and cost reduction can be achieved when compared to use of two single axis robots.
