2- Regen Drives
ECOVERT® FREQUENCY CONVERTERS :
Breuer frequency converter system solutions are used in all heavy duty industries such as oil & gas, mining, steel and cements industries as well as test bench technologies and special transportation equipment.
Our product line ecoVert® :
with its modular design and high power density makes it possible to offer an individual cost-effective solution to every customer. Drive concepts with ecoVert® are available in the power range 15 kW – 2700 kW for the voltage range 400 V – 1140 V. Due to DC-link connections it is possible to use external DC-power supply or to link various frequency converters. We can also supply any ecoVert® converter with internal PSU for single unit application or with central PSU (Power supply unit) for multi-drive solutions. Modularity enables high flexibility.
Our user interface is identical for all units and does not depend on power or voltage ratings. Its user-friendliness ensures quick installation and safe operation due to diagnostic tools as well as comprehensive protection concept. EcoVert® is symbol of quality, security and intelligent system solutions.

3- AFE-Regen Unit
In order to offer total ecoVert® solutions Breuer can supply an ecoVert® AFE-regeneration unit. Combination of the converter with the power regeneration unit is ideal for test bench technologies as well as multi-unit systems with shared intermediate voltage circuits.
To complete the portfolio we also developed a low harmonics converter that contains IGBT bridge instead of standard B6 diodes as rectifier. The harmonics can be compared with 18-pulse systems. The THD (Total Harmonic Distortion) is <5%.
4- Cabinet Converters
Control cabinet ecoVert® solutions offer cost-effective, flexible and reliable automation solutions in power range from 75kW up to 2700 kW.
In addition to the frequency converter, the cabinet can be supplied with the following:
- Protection class IP23 or IP54 / IP55
- Cabinet enclosure Rittal VX25
- Main isolating switch
- Semiconductor fuses
- Mains choke
- Mains filter class C3
- Power connection terminals
- Heat sink
Along with other standard fittings such as heating, lighting, top-mounted cable glands etc., Breuer specialize in customized control cabinets. Examples include: metal fittings on the cabinet, colour, special dimensions, sea water resistance, metal frame with increased stiffness, hand rails according to DNV, cooling (reduction or air suction not on the bottom), PLC integration, AFE-power regeneration,protection class up to IP65, etc. A comprehensive protection and diagnostic concept ensures easy installation, and secure operation in rough environments.
Breuer can deliver components as well as total solutions containing switch gear, transformers, frequency converters and motors. Our project engineers will offer you support in component choosing, system design, project design, installation and commissioning.
5- CUSTOM DESIGNS
Breuer offer customized solutions in various areas. We are the right partner to ask for economic technically advanced frequency control technology for asynchronous motors, permanent magnet synchronous motors or reluctance motors if you need an individual solution or a small product series. This could be test bench technology, specialty vehicles with hybrid, diesel-electrical or railway drives, hoist applications or port cranes.
For any application the frequency converter will be customized by our engineers in its hardware or software design. Software functions include Master/Slave, synchronization, load share and hosting control, modules for vertical and horizontal drilling, anti-skid, and anti-slip protection etc.
One partner – total services from an idea, through design and prototype building to full production.
Replacement of a 6-cylinder diesel engine with 18 litre cylinder capacity at a large construction machine by a speed / torque controlled, water-cooled 550 kW Breuer asynchronous motor with integrated frequency converter.
Especially in the metropolitan regions, the requirements for the reduction of exhaust and noise emissions are increasing worldwide. Even with large high-performance construction machines, an increasing market for machines with low-emission drive variants is developing.
In line with this trend, Breuer-Motoren developed an electric drive with an integrated frequency converter. In addition to the performance of the drive, the focus was on minimal design adaptations to the construction machine.
This enabled the customer to replace the diesel engine by the low-emission Breuer frequency converter motor in a short period of time.
