Technical knowledge guide

dCore, dGo, dMove or dPro?

Choose the right Dunkermotoren BLDC motor architecture based on control complexity, feedback, communication, safety and installation requirements.

Short answer

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

One Platform. Four Variants. Endless Possibilities.

The four variants differ not by performance, but by intelligence. They define which control, communication, and automation functions are available directly at the axis.

External controller

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.

Integrated speed control

dGo

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.

Integrated motion control

dMove

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.

Integrated servo drive

dPro

High-resolution feedback, field-oriented control, industrial Ethernet, diagnostics and integrated safety options.

Solves: precise, synchronized, networked and safety-related automation tasks.

Maximum freedom

dCore: keep the motor compact and the control external

The problem

Integrated electronics are not always the best fit

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.

The solution

Separate motor and controller

dCore provides the BLDC motor and rotor position feedback, while commutation, closed-loop control and communication are handled by an external controller.

Technical characteristics

  • Short motor package without integrated control electronics
  • Integrated Hall sensors for rotor position detection
  • Optional incremental or high-resolution encoder feedback
  • Flexible controller placement in the machine or cabinet
  • Suitable for centralized multi-axis architectures
  • Can be paired with suitable Dunkermotoren BGE controllers

Use dCore when

  • • the machine already has an external controller,
  • • electronics must be separated from heat or vibration,
  • • motor length must be minimized,
  • • controller selection and service access must remain flexible.

Simple integrated control

dGo: control speed without an external controller

The problem

A simple axis becomes unnecessarily complex

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.

The solution

Integrate commutation and speed control

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.

Technical characteristics

  • Integrated electronic commutation
  • Integrated 4-quadrant speed controller
  • Forward and reverse operation
  • Analog speed input and digital control signals
  • Reduced cabinet space and motor phase cabling
  • Factory parameterization for repeatable commissioning

Use dGo when

  • • the task is primarily speed control,
  • • start, stop and direction commands are sufficient,
  • • no fieldbus or positioning function is required,
  • • system cost, wiring and commissioning effort must be minimized.

Configurable motion

dMove: add motion profiles and CANopen without overengineering

The problem

Speed control alone is not enough

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.

The solution

Move motion intelligence to the axis

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.

Technical characteristics

  • Speed, current and basic position control
  • Stand-alone I/O operation without permanent bus connection
  • CANopen with CiA 301 and CiA 402 functions
  • Configurable digital inputs and outputs plus analog input
  • Homing and profile position functions
  • Drive Assistant 5 and MotionCode support

Use dMove when

  • • the axis must position or limit torque and current,
  • • stand-alone I/O or CANopen is required,
  • • decentralized logic should reduce PLC workload,
  • • dGo is too limited but dPro would be oversized.

High-end integrated control

dPro: precision, connectivity and safety at the axis

The problem

Advanced automation requires more than motion

Precise positioning, smooth torque, synchronized axes, real-time networks, diagnostics and functional safety often require several separate hardware components.

The solution

Combine motor, servo controller and feedback

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.

Technical characteristics

  • Integrated high-resolution encoder and field-oriented control
  • High-resolution speed, current and position control
  • CANopen, PROFINET, EtherCAT and EtherNet/IP
  • Synchronized operation through real-time network functions
  • Integrated STO up to SIL 2 and PL d, depending on version
  • MotionCode, diagnostics and extensive parameter access

Use dPro when

  • • high positioning accuracy or synchronized motion is required,
  • • the PLC uses industrial Ethernet,
  • • integrated functional safety is needed,
  • • diagnostic data and decentralized application logic are important.
