Compact 1-axis robot (electric cylinder) slider type with excellent durability applicable to the needs of the space saving and low cost is introduced.

SS type(Slider type)
Closed loop control achieves no step-out.
Use of a newly developed control system ensures constant torque at all times.

-Stroke:50 to 800mm
-Maximum speed:250 to 1000mm/sec
-Maximum payload(Horizontal):2 to 12



        TRANSERVO series
        1. New control method combines the best features of servo and stepping motors!
                  Stepping motors provide great features such as low cost , yet they have a drastic drop in torque at high speeds and heavy current consumption when stopped. The TRANSERVO by YAMAHA eliminates all these problems by adopting an innovative vector control method. In effect, the TRANSERVO delivers the same functions of a servo motor while using a lower cost stepping motor.

Energy saver!
      Control is basically the same as a servomotor so power consumption is kept to a minimum, which saves energy and helps cut down on CO2 emissions.

Perfect stop!
      Also perfect stop can be achieved as the same as with ordinary stepping motors so choose this setting if needed.

      2. Environmentally rugged resolver provides closed loop control
                The resolver used for detecting the motor position is the same reliable resolver as used in our high-level robots. Resolver offer stable position detection even in harsh environments containing dust or oil, etc. Addtionally the resolution of the resolver is 20480 pulses per revolution.
                The resolver is a magnetic position detector. Its structure is simple with no electronic component and no optical elements. One great feature compared to ordinary optical encoders is that there are very few points where a failure might occur. Vast quantities of resolvers are used in fields like aviation and the automobile industry where reliability is essential and also because they are highly tough in harsh environments with a low failure rate.

     1. Ideal 4-row circular-groove 2-point contact guide gives longen service life
                  A newly developed module guide is employed with a 4-row circular-groove 2-point contact guide built into a very compact actuator . The guide maintains a satisfactory rolling movement with minimal ball differential slip, even if a large momentum load is applied or the installation surface accuracy (flatness) is bad. Rugged design ensures that breakdowns from problems like abnormal wear will seldom occur.

      2. High-speed operation slashes production time!
                    Making maximum use of advantages offered by the vector control method, the TRANSERVO maintains a constant payload even in the high-speed range. This helps to drastically cut down on the tact time. By combining this feature with high-lead ball screws, the TRANSRERVO has achieved a maximum speed of 1 meter per second* which is faster than any single-axis servo motor.

      3. Space-saving models newly added to lineup

        Space-saving models allow a more efficient layout. Compared to a straight model, the overall length is reduced by up to 143.5mm. This space saving is achieved by folding the motor and makes it possible to design a more efficient layout.


      Excellent maintenance ability
        Normally, the belt cover is secured by the screws. However, SS type space saving model uses a hook structure. So, the belt cover can be detached easily by removing only two screws from the shutter support plate.

      4. Clean type electric cylinders are also added to the lineup.
         Models applicable to cleanliness degree class 10 are also added to the lineup. These models are suitable for work in the clean room.
