Motors and Drive System for Bioreactor - Stegia



Motors and Drive System for Bioreactor

Customer: Bioprocess Control

Bioprocess Control is a technology and market leader in the area of advanced instrumentation and control technologies for research and commercial applications in the biogas industry.

Stegia have previously worked together with Bioprocess Control in developing the AMPTS II system and we were asked to be a partner when they wanted to upgrade their Bioreactors in a similar way. The bioreactors manufactured by Bioprocess Control are of continous stir type (CSTR) and are specifically designed for scientists and process engineers to simulate full-scale fermentation processes in laboratories.

The old system was equipped with a brushed DC-motor and a gearbox, Bioprocess wanted to extend the lifespan of the system and migrate to a brushless motor without the need for a gearbox.

Stegia assisted Bioprocess control with both mechanical and electrical design to develop the new drive system. Some of the activities performed were:

  • Design of 3-phase driver PCB with semi-close loop operation for low energy consumption.
  • Firmware development
  • Design of anodized aluminum housing.
