HANNZ MOTROLproduct
DynaStation
Dynastation GTB series is a high
precision servo reducer unit.
Solving the conventional problems of automation field,
Using original Zero backlash mechanism and Roller
Gear Cam structure, ealize high precision,
r light weight, and compact design.
Characteristics of the product
GTB High ratio type
Zero backlash mechanism without
abrasion compact high-strength body
-
Roller gear cam reducer
The movement of the output is generated by the roller gear cam mechanism without backlash. with the preload, the roller gear cam makes a rolling contact, so it has zero backlash transfer characteristics as well as wear free and long term stable performance
-
BLACK FINISH high-strength body
The housing achieves high rigidity and compact deign by stress optimized design and high strength precision casting. The surface has a special black finish with excellent corrosion resistance.
GTB Motor direct type
Design that cope with two type
of reduction characteristics
-
Reduction ratio select system (PAT.P)
Product selection is available in two types: high ratio type for high torque and motor direct type for high accuracy.
-
Stable vertical and
plane installationThe product can be installed in any direction, either plane or vertical. Except for the motor direction, the installable surface is arranged in all the other direction, so it can be used for various installation methods. In addition, since the front and rear mounting positions are the same, it is possible to arrange the position of the motor and the position of the output hole variously.

caution
- ※ Be sure to install a servo motor with brake type so that the table can safely stop at power failure if torque is applied due to gravity. etc.
- ※ When selection the motor, please make sure to satisfy all the requirements such as allowable torque motor driver regeneration resistance specification.
- ※ Read the manual procedures when assembling the motor.
- ※ Please contact us for further details.
