For drive design
requiring high precision ShinMaywa Industries 
Series
DD motors that combine
design flexibility with high performance
When designing equipment that demands high precision and reliability, factors such as optimal structure and appropriate sizing are just as important as performance.
ShinMaywa’s BUILT-IN DD series delivers not only high precision and reliability but also stable rotation with low torque ripple;
furthermore, the availability of large hollow-bore and frameless configurations allows for highly flexible drive system designs.
We support the selection of the optimal motor to meet your specific requirements, offering everything from standard models to custom designs and small-batch production.
-
STRENGTHS／01
Design tailored to your requirements and flexible customization options.
We design motors tailored to your specific requirements, including torque, rotational speed, size, temperature conditions, and environmental conditions, and can supply them starting from a single prototype.
-
STRENGTHS／02
Smooth and stable rotation thanks to proprietary technology
Its unique low-torque ripple design ensures smooth rotation and high speed stability.
It can be used with confidence in applications requiring high precision, such as high-precision machining equipment and inspection devices. -
STRENGTHS／03
Large hollow structure enables highly flexible equipment design.
The large hollow structure ensures flexibility in the placement of wiring, piping, and shafts.
This contributes to making the device more compact.

For highly flexible drive system design
FRAMELESS
MOTOR
Frameless motor (custom made)
With its frameless structure that is easy to integrate into equipment structures, it is ideal for equipment where flexibility in layout and hollow design is important.
We also offer custom designs tailored to your specifications. -
For thinner, lighter, and lower-cost
FRAMELESS
MOTOR
Frameless motor (mass production model)
Achieving a 75% reduction in thickness and weight compared to conventional models, it can be directly integrated while maintaining high output, dramatically increasing design flexibility for robot joints and other components.
"This is a low-cost, mass-produced model with fixed outer diameter and specifications." -
For lower vibration and high precision
SLOTLESS
MOTOR
Slotless Motor
The slotless design further reduces torque ripple, resulting in smoother and more precise rotation.
It also supports faster processing speeds. -
For high speed and high precision
AIR SPINDLE
UNIT
Air Spindle Unit
An air spindle unit that achieves both high speed and high precision.
By employing high-precision hydrostatic air bearings, low NRRO, low friction loss, and low heat generation are achieved. -
For stable control of DD motor
