A visual engineering perspective

DTFC modular software architecture

Application, system, hardware-abstraction, and driver layers separate product behavior from target-specific implementation.

  • Application-specific implementation at the top
  • Reusable system functions and defined interfaces
  • Hardware abstraction separates target-specific drivers
Engineering approach

From architecture to application.

01 / ENGINEERING APPROACH

Define the system behavior

Bring together operating modes, motor and load characteristics, sensing, communication, and user-interface needs.

02 / ENGINEERING APPROACH

Coordinate the electronics

Evaluate motor-drive stages, application controllers, and interfaces as part of an integrated product architecture.

03 / ENGINEERING APPROACH

Build from relevant experience

Published projects include controllers with active PFC and multiple inverters, temperature-control functions, and HMI implementations.

04 / ENGINEERING APPROACH

Laundry as an integration example

The supplied application material describes DTFC in laundry drives with loaded startup, high-speed spin operation, load-unbalance estimation from motor signals, and controlled deceleration with DC-bus management. These functions illustrate the connection between motor control and the complete appliance.

05 / ENGINEERING APPROACH

Build product variants on a shared firmware foundation

For laundry programs, configure modules such as load-unbalance analysis, extraction monitoring, motion sequences, HMI, and communication around the reused control library. The supplied laundry material also compares separate-board and integrated control/inverter architectures for evaluating system cost.
