Micro Direct Drive Motor

World-class AC servo motors are now available.
Miniature AC servo motor (micro DD motor) from Microtech laboratory is a compact designed high-performance servo motor with integrated high resolution encoders and offers very poweful torque at low speed from very compact body, which makes possible a gearless structure and therefore its gearless structure brings a lot of benefit for users.
For example,
-Fine positioning 
-Great acceleration 
Application examples
-High precision positioning applications
-Robot arms
-Small scalar robots
-Bilateral master/slave control
-Other gearless structures
Theta-axis motion

Desire: Reducing takt time and size reduction together.


Proposal: Placing Micro DD motor for driving theta-axis on the end effector. Great features such as high torque and low speed help you to achieve your goal. Also gearless structure helps to enhance accuracy.

Development of SCARA

Challenge: Development of SCARA


Proposal: Micro DD motor can be used easier and is good for direct teaching, external force detection and silence which are required to Cobot.

Torque control

Challenge: Development of robot hand that can grab many kinds of things.


Proposal: Micro DD motor helps you to achieve your goal by high responsiveness of torque control and high backdrivability.

Substitute for rotary actuators.

Desire: Although a hollow shaft structure is prerequisite in your design, the accuracy can not be compromised too.


Proposal: Micro DD motors hollow shaft type can be a substitute for rotary actuators.

Robustness against the load on the shaft.
