Microtech Laboratory for small direct drive motors
About μDDmotor(direct drive motor)
What is DD motor？
DDmotor is the servo motor that has high acceleration and positioning,
Which also specialized in using for gearless.
DDmotor has characterristics of low speed and high torque (compared to general servo motors) because this motor is assumed that it will drive directry without using a gear(a deceleration mechanism).Its equipped sensor specialized in high-precision positioning, and It is possible to receive the shaft load directly by adopting high-load bearing as standard.
Advantages that can be generally obtained by using a gearless structure are described below.
QuietizationThis motor leads noise reduction since it has
no vibraition sound.
High precisionIt is possible to determine high precision
positioning by eliminating a machanical error
due to backlash.
Weight and spase saving 
Improving acceleration
BackdrivabilityIt is a characteristic that is advantageous when
an operator provides tactile feedback for master-slave control.
What is μDDmotor?
It’s the world`s smallest direct drive motor！
MTL has the strength unique to manufacturers specialized in a rotary encoder.
We have realized small sized and hollow shaping while retaining the goodness of the conventional DD motor.
High torque
About 5 times torque density
(compared to AC servo mortor as
standard)
Ultra compact size
The world`s smallest class
(compared to DD mortor as
standard)
Hollow shaft
Hollow late 35%
(it`s a top class in theservo
motor industry)
Product lineup
We have a rich lineup of small direct drive motors.

Case studies and customizing unique to μDDmotors
Double-armed robot
that transmits bodily sensations
「GP-Arm」
It can share force tactile and visual information with a robot in a distant place in real time.In the future, it will maybe become an avatar and be possible to directly teach not only location information but adjustment and visual information.

Tap in the hollow shaft μDD motor
A rotary joint can be connected using a tap.
This is the best in rotational drive and fixation by sucking on index table, and it is also used in a end effector to transport small parts.
