dCore
Compact BLDC motor architecture with Hall feedback and flexible connection to an external controller.
Solves: limited installation space, centralized electronics and freedom of controller choice.
Technical knowledge guide
Choose the right Dunkermotoren BLDC motor architecture based on control complexity, feedback, communication, safety and installation requirements.
dCore is for external controller. dGo provides simple integrated speed control. dMove adds configurable motion control with I/O or CANopen. dPro provides high-resolution servo control, industrial Ethernet and functional safety options.
Architecture overview
The four variants differ not by performance, but by intelligence. They define which control, communication, and automation functions are available directly at the axis.
Compact BLDC motor architecture with Hall feedback and flexible connection to an external controller.
Solves: limited installation space, centralized electronics and freedom of controller choice.
Cost-optimized integrated commutation and speed control for simple analog and digital machine interfaces.
Solves: unnecessary cabinet components, wiring and commissioning for basic speed axes.
Configurable speed, current and positioning functions with stand-alone I/O or CANopen communication.
Solves: motion tasks that need more than speed control but not a high-end servo system.
High-resolution feedback, field-oriented control, industrial Ethernet, diagnostics and integrated safety options.
Solves: precise, synchronized, networked and safety-related automation tasks.
Maximum freedom
The machine may already use a central servo system. The controller may need to remain in a protected cabinet, or the motor location may be exposed to heat, vibration or very limited installation space.
dCore provides the BLDC motor and rotor position feedback, while commutation, closed-loop control and communication are handled by an external controller.
Simple integrated control
Many conveyors, pumps, fans and roller drives only need speed, direction and braking. A separate controller, motor phase cabling and fieldbus setup add cost without improving the task.
dGo combines the motor with compact 4-quadrant electronics. The axis can accelerate, run and brake in both directions through straightforward analog and digital signals.
Configurable motion
The axis needs current limitation, positioning, homing or configurable I/O. At the same time, high-resolution servo feedback and industrial Ethernet would add unnecessary cost and complexity.
dMove integrates a configurable 4-quadrant controller for speed, current and positioning functions. It can work stand-alone through I/O or communicate via CANopen.
High-end integrated control
Precise positioning, smooth torque, synchronized axes, real-time networks, diagnostics and functional safety often require several separate hardware components.
dPro integrates high-resolution feedback and advanced motor control. Depending on the version, it supports I/O, CANopen, PROFINET, EtherCAT or EtherNet/IP, plus Safe Torque Off.
