KOSTAL variable frequency drives in mobile electrical drive technology: Flawless operation in all situations

In the field of mobile electrical drive technology, there are countless units to be controlled: Compressors for air conditioning systems in hybrid buses, compressors for pneumatic air brakes, hydraulic units in excavators, injection and fuel pumps, auxiliary power units and electrical drive trains. They all differ in terms of their function, but they also all have something in common: They are always on the move. The constant movement demands a lot from the required variable frequency drive. All the better then if it is of the robust variety and meets all the requirements of mobile auxiliary units.

KOSTAL variable frequency drives in mobile electrical drive technology: Maintenance-free – even with the strongest vibrations

In the field of mobile electrical drive technology, vibrations are a common issue simply because of the constant movement, be it a bus driving over a road full of potholes or an excavator on uneven ground. Therefore, in such cases, it is good if not only the electric motor used but also the variable frequency drive can handle these vibrations.

The mobile variable frequency drives from the KOSTAL INVEOR family are equipped for all applications in mobile auxiliary units: thanks to the massive adapter plates and robust construction, forces and vibrations of up to 5G are not an issue at all. The patented pulse injection process also ensures maintenance-free operation because it enables drive control without delicate sensors.

Mobile electrical drive technology: compactly integrated with KOSTAL variable frequency drives

A compact design is absolutely essential for auxiliary units in mobile electrical drive technology. This is because a low weight and a hidden design ensure better aerodynamics and consume less energy. This allows hybrid or electric buses to cover significantly longer distances. In addition, the compact construction gives you the greatest possible flexibility in terms of where you position the drive technology in the application. For totally new design options.

The KOSTAL variable frequency drives from the INVEOR family are motor-mounted drive controllers that do not need long cables or control cabinets. They are positioned directly on the motor and therefore allow for the most compact designs without unnecessary additional weight. With the corresponding adapter plate, they also fit with all kinds of motors – for a space-saving design in all areas of mobile drive technology.

Prepared for all weathers: Mobile electrical drive technology with KOSTAL variable frequency drives

Mobile auxiliary units in electrical drive technology are exposed to many different weather conditions, be it the air conditioning system on the roof of a hybrid bus or the pneumatic air brake under the vehicle. The problem is that not every variable frequency drive is suitable for such conditions.

Our motor-mounted variable frequency drives, such as the KOSTAL INVEOR M and the KOSTAL INVEOR MP, are equipped for all weather conditions with their IP 65 protection class – from the hardest rainfall, hail, dew/ice and snow to heat waves of up to 50 °C. This means you can always rely on your mobile auxiliary units to function – and keep your customers happy in all situations.

Mobile auxiliary units with battery drive – flawless operation with variable frequency drives from KOSTAL

Especially in the field of mobile electrical drive technology, batteries have become indispensable, both in vehicle technology for electric vehicles and hybrid buses as well as in railway and rail transport technology. However, batteries can only supply your mobile auxiliary units with DC voltage. It would be a good thing if the variable frequency drive used could also handle this function, wouldn't it?

The motor-mounted variable frequency drives from KOSTAL can work with both AC and DC voltage. This gives you the greatest possible flexibility when choosing the voltage source, while at the same time you benefit from clear and simple commissioning. Because you can control all voltage sources with just one type of variable frequency drive, there is also only one operating concept.

Increase your energy efficiency: with KOSTAL variable frequency drives in mobile applications

Increasing energy efficiency is an important issue in mobile applications. Because the less energy a unit consumes, the lower your bills and carbon emissions – over the same run time. However, this calculation only works if the variable frequency drive is compatible with the latest motor standards.

Our variable frequency drives in the KOSTAL INVEOR family are motor-mounted and energy-efficient drive controllers of the latest generation. They control all electric motors up to synchronous motors of energy efficiency class IE5. In terms of the Ecodesign Directive, you are prepared for the next few years and are also contributing to a more climate-friendly environment – without having to sacrifice performance.
