Flaps Motor Control Module (FMCM)
DAL A FPGA-Based Motor Control Unit
- 2 KW Brushless DC Motor Controller
- DAL A Certifieable Development
- DO160g Qualified for non-pressurized environment
The FMCM is a motor controller for the electrical FLAPS actuation of a medium sized turboprop Part-25 Aircraft
The FMCM controls the speed, and direction of one 3 phase motor based on the speed command received via CAN and the actual motor speed received from a resolver attached to the motor.
- The FMCM controls the motor POB according to command received via a CAN bus via a discrete signal
The FMCM sends actual motor speed, status, and BIT detected failures on CAN bus.
Top Level Architecture
All functions of FMCM are implemented in an FPGA.
Enclosure & Environmental Qualification
The FMCM is built into a robust sealed aluminum enclosure. Environmental qualification is performed according to DO160 for non-pressurized environment.
