Orbray's micro motor BMN02-0593 belongs to the world's smallest class of hollow shaft motors. Since optical fibers can be run through the hollow shaft, it is possible to construct ultra-compact optical actuators, which are expected to contribute to breakthroughs in leading medical and industrial fields, such as OCT* and endoscopy. Based on this hollow shaft motor technology, Orbray developed an Optical Radial-scanning Bore Inner Digitizer for use in the industrial measurement field. This system is capable of 3D measurement of the inner circumference of small-diameter holes in components – data which was previously limited and challenging to collect. Orbray aims to meet the needs of cutting-edge medical and industrial fields with our hollow shaft micro motor.

* Optical Coherence Tomography = technology that uses near infrared rays to take tomographic images of samples.

Application Example

  • Medical / analytical measuring device
  • Development of evaluation technology for internal state and progression of wear of important equipment such as infrastructure equipment, vehicles, and aircraft
  • Construction of ultra-compact manipulators that have limited wiring space
