Domel Group and European Precision Electric Motor Engineering
Slovenian industrial manufacturer Domel d.o.o. has been a technological leader in high-speed electric motors, vacuum suction units, and electronically commutated blowers for decades.
Established in 1946 in Železniki, the enterprise operates automated production plants across Slovenia, testing laboratories, and international facilities. In May 2026, the company opened its Trata 2 production facility in Škofja Loka to expand capacity for permanent magnet synchronous motors (PMSM).
Domel solutions power professional cleaning equipment, cleanroom ventilation, automotive assemblies, and medical instrumentation. All facilities comply with ISO 9001, ISO 14001, and IATF 16949 standards.
Bypass Vacuum Motor Units for Heavy-Duty Commercial Cleaning Machinery
For commercial floor scrubbers, carpet extractors, and street sweepers, Domel produces bypass vacuum motor units across series 491, 492, 496, and 498. The bypass architecture strictly separates the working suction airflow from motor winding cooling.
Moisture and chemical vapors travel through the centrifugal impeller housing and exit via tangential or radial diffusers, while motor windings are cooled by clean ambient air pulled by an independent top fan.
This design prevents electrical short circuits, protects commutators from corrosion, and ensures dependable operation in aggressive wet extraction environments.
Brushless EC Superflow Blowers for Continuous Industrial Aspiration
For centralized vacuum extraction, pneumatic conveyance, and laser fume filtration, Domel engineered high-speed brushless EC motors across series 790, 792, and 794.
The 792 Superflow series achieves rotor speeds up to 60,000 RPM under digital inverter control, delivering over 20,000 hours of continuous operating life without maintenance.
Blower assemblies incorporate precision bearings resistant to dynamic radial loads and support speed modulation via 0–10V, PWM, or Modbus. The brushless architecture eliminates carbon dust emission, making units ideal for clean industrial environments.
Low-Voltage BLDC Drives for Mobile Robotics and AGV Automation
The rapid acceleration of automated intralogistics imposes rigorous constraints on the power density, efficiency, and physical envelope of traction drives.
Domel low-voltage brushless DC motors and drives across series 720, 725, 730, and 740, designed for safe operating voltages of 12V, 24V, and 48V DC, provide the motive power for automated guided vehicles (AGV), autonomous mobile robots (AMR), and precision medical positioning equipment.
The Inner Runner architecture (rotor interior with high-coercivity NdFeB neodymium magnets) yields minimal rotational inertia and exceptional acceleration dynamics in rapid-cycling servo mechanisms.
The Outer Runner variants (external rotating rotor series 725) generate substantial continuous torque at lower rotational velocities, enabling the construction of compact, gearless direct-drive motorized wheels that maximize battery efficiency and travel range.
Innovative Cathode Blowers for Zero-Emission Hydrogen Fuel Cells
As part of the global transition toward sustainable zero-emission power generation, Domel engineers created specialized Cathode Blowers for proton-exchange membrane fuel cells (PEMFC).
Generating electrical power efficiently inside fuel cell stacks requires supplying precisely metered volumes of ambient oxygen under constant pressure to the cathode reaction surface.
The process air path within Domel cathode blowers is completely oil-free: precision gas-dynamic or specialized sealed bearing architectures eliminate any trace of lubricant aerosol that could irreversibly poison expensive platinum catalyst layers on the membrane.
Capable of rotational speeds up to 100,000 RPM, these compact brushless units withstand dynamic vibration and deliver instantaneous response times during rapid vehicle acceleration or variable grid loading.
Domel Tehtnica Centric Analytical and Clinical Centrifuges
The Domel Tehtnica division combines Slovenian precision manufacturing with digital microprocessor control to deliver premium clinical and laboratory equipment.
The centerpiece of this product line is the desktop centrifuge family known as Centric (including models 220, 250, 260, 350, 400 R, alongside specialized Centric MF 48 and CF 48 systems).
These centrifuges utilize in-house manufactured brushless induction drives that guarantee quiet operation, vibration-free spinning, and rock-solid velocity stability during biological sample separation.
Refrigerated models (designated with suffix R) maintain chamber temperatures accurately between -20 °C and +40 °C even at maximum centrifugal acceleration, preventing thermal breakdown of sensitive blood fractions and proteins.
All units are fully certified in compliance with European in vitro diagnostic medical device directives (IVD).
Engineering Selection, Energy Audits, and Technical Integration
Selecting Domel industrial electric motors and blowers requires technical analysis of aerodynamic resistance and electrical drive coordination. Our engineering team reviews existing installations to identify optimal motor upgrades that replace legacy motors, reducing power consumption by 20% to 40%.
We deliver comprehensive technical documentation, including certified PQ curves, 3D CAD models, factory compliance sheets, and wiring schematics. All shipments are supplied with complete customs clearance, cargo transit insurance, and comprehensive operational warranties.
