RTA - BSD 02 - Open-Frame, Stepping Motor Drive

Stepping motor drive open-frame BSD 02 ( ADVANCED )

( 24 - 48 VDC 0.7 - 2.2 Amp )


  • New series of microstep stepping motor drives specifically developed for small and mid-size stepping motors.
  • Ultra-compact and optimized design to reduce space and cost, combined with Adaptive Microstepping technology ensuring noise and vibration suppression.
  • Target: simple and effective motion control solutions requiring low power, high precision, smoothness of movement and low acoustic noise.
  • Ideal solution to replace integrated circuits and self-made, low power drives. The perfect choice for small routers, medical, 3D printers and all types of compact machines.


  • Full digital microstepping drive.
  • Adaptive microstepping up to 3.200 step/rev.
  • Intelligent management of the current profile that achieves good results in terms of smoothness of movement, low noise and vibration control.
  • A highly sophisticated control system, preserving anyhow the traditional ease of use of R.T.A. drives.
