Dunkermotoren has expanded its motion portfolio with system-level brushless DC (BLDC) motor solutions tailored for medical, industrial, hydraulic, and process pump systems. The modular architecture consolidates motor mechanics, drive electronics, sensor feedback, and communication protocols into a unified drive package to streamline OEM integration and bill-of-materials management.
Application Sectors and Operational Demands
The drive solutions address specific fluid-handling operating parameters across diverse operating environments:
- Medical Technology: Supports hemodialysis and fluid management systems with vibration-free, low-noise operation and reproducible flow delivery during extended treatment procedures.
- Hydraulic Systems: Delivers dynamic on-demand pressure regulation under fluctuating mechanical loads and harsh environmental conditions across rail and mobile equipment.
- Cooling and Process Circulation: Uses variable-speed control to adjust flow and pressure in real time, cutting energy consumption in continuous HVAC and fluid loops.
- Dosing and Metering Equipment: Provides high-accuracy rotational control for repeatable volumetric dosing in automated filling, chemical processing, and water treatment operations.
Scalable Control and Networking Platforms
Dunkermotoren offers three tiered control architectures to match specific automation complexity:
Dunkermotoren offers three tiered control architectures to match specific automation complexity:
- dGo Platform: Provides standalone four-quadrant speed regulation, directional switching, jam detection, and custom speed profiles via analog and digital inputs.
- dMove Platform: Adds CANopen fieldbus communications and digital interfaces to enable positioning routines, torque control, and remote monitoring of speed, current, and temperature.
- dPro Platform: Features field-oriented vector control and interfaces with industrial Ethernet protocols—including PROFINET, EtherCAT, and EtherNet/IP—delivering high dosing precision, Safe Torque Off (STO) functionality, and real-time telemetry for IoT and predictive maintenance systems.
OEM customization options include tailored shaft geometries, specialized motor-to-pump mechanical interfaces, modular planetary or worm gearboxes, and integrated encoder systems.

This section details technical specifications not included in the original news release.
Electronically commutated brushless DC motors utilize permanent magnet rotors (commonly using neodymium-iron-boron alloys) paired with three-phase stator windings. Commutation is governed electronically via internal Hall-effect sensors or high-resolution magnetic and optical encoders, eliminating mechanical brushes and commutator wear. In pump drive applications, field-oriented control (FOC) algorithms decompose stator currents into torque-producing and magnetizing components, minimizing torque ripple and maximizing motor efficiency across variable rotational speeds.
The dPro platform incorporates hardware-based Safe Torque Off (STO) conforming to IEC 61800-5-2 standards (reaching SIL 3 and PL e safety ratings), which cuts gate driver power to internal power MOSFETs or IGBTs to prevent unintended shaft rotation during emergency stops without disconnecting intermediate DC-link supply power. Drive housings are engineered to achieve industrial enclosure ratings ranging from IP54 up to IP65 or IP69K, utilizing radial shaft seals, hermetically sealed potting compounds, and corrosion-resistant stainless steel hardware to prevent liquid ingress in washdown and chemically aggressive environments.
