DD Motor

NEW

DD Motor ZMD-1010 ZMD-1007 ZMD-1003

Realizing outstanding high speed and
precision performances thanks to its small and compact design

Features

Outer rotor mechanism
The outer diameter's compact design enables to drive directly the roller, making it suitable for indexing rotation
High-resistance bearings
Simple and rigid structure for a higher load resistance
Hollow diameter φ50mm
Wiring and piping can be easily stored in the hollow space of the motor, reducing the istallation space.
Low price
Model's size reduction leads to a more competitive price matching today's markets needs
Short lead time/ quick delivery
The reduction of the components and a smarter stock arrangement critically reduce the production lead time
What is a Direct Drive Motor?

A DD Motor can transmit the torque of the electric motor directly to the driving objects,
without the use of any reductions such as belts, pulleys or reduction drives.

  • | High efficiency
  • | Low noise
  • | Outstandig precision
  • | High reliability
  • | Maintenance-free
