Space-rated drive electronics

MACCON supplies motor power and control electronics for space programs. These are designed
and built to customer specification. However all new designs are based on established technology,
which has been successfully implemented on previous space programs – see features and
examples below. Please download the brochure on the top right-hand side for more information about the electronics which we designed for projects such as BIOLAB and MHS (microwave humidity scanner).

Our offering:

• Motor power stages
• Digital controllers
• Control of current, velocity, and position
• Support of position feedback devices
• Support of host command interfaces
• Customized software applications
• Full In-house design, analysis, test and qualification by MACCON
