Brushless DC direct drive motor
Responding to "true needs"—that is our theme. Currently, most DD motors available on the market are supplied based on the manufacturer's convenience rather than the needs of the users. This has the advantage of being available at a low price. On the other hand, it often fails to meet specific requirements based on the intended use. ShinMaywa proposes a new type of "DD motor" to address these frustrations. ShinMaywa's AC servo motor "BULT-IN-DD series" is a synchronous motor type (brushless DC motor type) DD motor developed for direct drive robots. The "BULT-IN-DD series" is equipped to handle various special specifications and supports companies that are challenging new endeavors from a technical standpoint. Please feel free to contact us.
