Laboratory-scale centrifuges are used in chemistry, biotech, and clinical medicine for isolating and separating liquids. Speed and capacity requirements vary, but high dynamics and close tolerances are common needs across all centrifugation applications. In addition, providing laboratory workers with a friendly work environment requires that centrifuges operate at low noise levels with easy-to-use and simple user interfaces.
The Power of BLDC drives
Brushless DC (BLDC) or electronically commutated (EC) motors offer several advantages over brushed DC motors:
- Increased efficiency and reliability
- Reduced noise and vibration
- Longer lifetime (no brush and commutator erosion)
- Elimination of ionizing sparks from the brushes
- Overall reduction of electromagnetic interference (EMI)
- High torque to weight ratio.
BLDC drives need several electronic components for motion control and power amplification. With the Trinamic Motion Control Architecture, we offer a complete toolbox to create powerful applications. And our advanced technologies like Field-Oriented Control enable increased performance and efficiency.
Field-Oriented Control is a powerful control strategy to control torque of three-phase AC machines and stepper motors with high accuracy and bandwidth. It can be implemented in either hardware or software.
Bitstream-based control is the natural evolution of this development and acts directly on the bitstream and thereby supersedes the digital filter-based control strategy. The control scheme is superior in performance and accuracy in comparison with state of the art control strategies and voltage modulators.
