FDB Technology

 

The BLDC FDB SP2B motor combines expertise and know-how with maximum precision. The advantages of a brushless DC motor are brought together with the cutting-edge technology of the FDB motor. FDB stands for „Fluid Dynamic Bearing“. High-speed running, low vibration and a long lifespan are only a few of the numerous virtues. Especially in the fields of „3D Laser Scanning“, „LiDAR“ and „Virtual Reality – Laser Tracking Scanner“ the motor with its hydrodynamic bearing system is the perfect choice for high-precision applications.

Our combination of BLDC and FDB

 

A BLDC motor is commutated brushless and therefore electronically. Brushes are redundant, since the torque is a result of the electronic impact of the BLDC motor on the commutator. That is why there are fewer components to wear out, the motor is extremely long-lasting and reliable.   

 

The BLDC motor offers numerous additional advantages:

  • high efficiency
  • extremely quiet running and ultimate life expectancy due to the brushless technology
  • optimized electromagnetic design to prevent vibration, noise and jitter
  • no wear parts

The FDB motor has initially been developed to fulfil the high-precision mechanical standards and the required long service life for the hard disc industry. Due to the fluid dynamic bearing, the limited precision of ball bearings is eliminated, the non-repeatable run out is minimized and the level of noise is lowered. As a result, the FDB motor offers superior reliability.     

 

The FDB motor offers superior performance in terms of:

  • extremely quiet and accurate running
  • low vibration
  • low run out (NRRO below 40 nm)
  • low level of noise
  • extremely long-lasting, since there a no wear parts
  • high speed up to 15.000 rpm
  • wobble error < 3"low
  • energy consumption

Safety Technology

High accuracy, low vibration, a wide field of vision as well as high axial and radial stiffness are only a few of the numerous virtues of our FDB motor in the area of safety technology. The motor allows high density and  a wide viewing angle. Thanks to the compact design also smaller constructions in this application area are possible. The fluid dynamic bearing comes without the limited precision of ball bearings and minimizes the non-repeatable run out to optimize the steadiness.
