Stepping servo system Si servo3

Si servo3
No compromise on position, speed and torque!
We have acquired the ability to accurately execute the control elements required
by our customers with the latest technology.

 Features

1.  Si servo3 has lineup of 9 types of motors.

Speed & Torque balance N-T
We have motors from 0.05N to 2.0N type.
We have newly added 0.7N type / 0.8N type motors to our lineup.
In addition, in the Si servo 3 series, we have standardized motors with characteristics that cause little torque reduction even in the high speed range.
In general stepping motors, torque reduction in the high speed range is a problem, but Si servo 3 outputs sufficient torque even in the high speed range and realizes high tact operation.

2. Super high speed motor that rotates at a maximum of 6000 rpm.

Speed and amplitude
With a general stepping motor, the limit is about 3000 rpm to 4000 rpm, and the output torque in this rotation range was not at a practical level.
In Si servo3, we have added a motor that can be practically used up to 6000 rpm in the 0.3N type to the lineup.

3. Equipped with a high resolution encoder.


All models are equipped with a 10,000 pulse / rev encoder.
Highly accurate feedback of position information and speed information realizes highly accurate positioning and smooth operation without attachment and detachment.
It has the ability to generate up to 200% torque depending on the deviation of the feedback.

4. NEW function was developed [Toruqe research]!


Various linear motion mechanisms are affected by mechanical load fluctuations, and it is not possible to control accurate pressing force only by torque limiting.
With Si servo 3, you can control the exact pressure by learning the load without using feedback such as sensors.
In addition, fine pressure adjustment is also possible.
