Integrated Electronics for Decentralized BLDC Drives

Dunkermotoren is releasing the dGo motor family, a series of brushless direct current (BLDC) drives equipped with integrated commutation electronics to simplify decentralized drive concepts. These actuators are engineered for conveyor rollers, fluid pumps, ventilation fans, and auxiliary axes in industrial automation where reproducible speed control is required without the overhead of fully programmable servo systems.

Streamlining Decentralized Drive Concepts
Standard automation systems frequently utilize auxiliary axes that require stable speed regulation rather than complex positioning profiles. Deploying high-performance servo controllers for these basic tasks increases engineering effort, wiring complexity, and commissioning time. The dGo series addresses this technical gap by embedding the necessary control intelligence directly within the motor housing, bypassing the need for separate external controllers and reducing the overall hardware footprint.

Depending on the specific model, motor speed is regulated through supply voltage modulation, an analog signal, or pulse-width modulation (PWM) inputs. Digital inputs and outputs manage core operations such as start, stop, and directional reversal. Because the system operates without fieldbus communication protocols, machine builders can integrate these motors directly via standard programmable logic controller (PLC) I/Os. Michael Burgert, Product Manager at Dunkermotoren, notes that the hardware provides reliable BLDC performance and simple control for motion axes that do not necessitate full servo programmability.

Motor Specifications and OEM Parameter Configuration
The product family consists of three distinct series—the BGA 22, BG 42, and BG 45—to accommodate varying power requirements and installation constraints within a unified motion control platform.

The BGA 22 dGo is designed for restricted installation spaces. It utilizes an ironless core architecture that eliminates cogging torque, resulting in quiet operation and smooth rotational mechanics. This model delivers a continuous power output of up to 24 watts and achieves peak power outputs up to 236 watts.

For applications demanding higher continuous torque, the 42-millimeter diameter BG 42 dGo provides up to 96 watts of continuous power and 214 watts of peak power. It features an integrated four-quadrant control system, enabling controlled acceleration, active braking, and directional reversal, making it highly suited for transport lines and material handling systems requiring frequent reversing cycles.

The BG 45 dGo extends these physical capabilities into harsher industrial environments, offering enclosure protection ratings up to IP65 and multiple hardware mounting configurations. Across all models, original equipment manufacturers (OEMs) can pre-configure operational parameters at the factory. Custom functional sequences, including fixed rotational speeds, specific acceleration and deceleration ramps, current limits, and autonomous blockage detection, are written directly into the motor electronics. By shifting these sequences to the drive, the main control hardware processes fewer localized logic tasks.

Additional Context
This section details technical specifications and competitive benchmarking not included in the original news release.

In the industrial motion control sector, entry-level brushless DC motors with integrated speed controllers are evaluated based on power density, stator design, and control interface simplicity. The dGo series benchmarks against established integrated drives such as the FAULHABER BX4 series with built-in speed controllers and ebm-papst's VDC motor lineup. A primary technical differentiator in this hardware category is the deliberate reliance on analog and PWM signaling rather than fieldbus protocols like CANopen or EtherCAT, which drastically reduces networking hardware costs and microprocessor overhead on the main machine PLC.

The IP65 rating on the BG 45 model aligns it with ruggedized industry standards seen in maxon's IDX compact drives, providing ingress protection against dust and low-pressure water jets for localized deployment in wet manufacturing environments. Furthermore, the BGA 22's ironless stator design provides a linear speed-torque gradient comparable to premium coreless competitors, specifically optimizing low-speed stability by eliminating magnetic detent torque.
