Mahle showcasing new SCT motor at IAA Transportation


On the upcoming IAA Transportation commerce honest in Hanover, Germany, MAHLE will premiere its new SCT electrical motor (Superior Steady Torque), which supplies extraordinarily excessive steady energy and is due to this fact particularly suited to business automobiles. (Earlier publish.)

As well as, MAHLE is presenting its latest programs options for battery electrical drives, gasoline cells and cleaner combustion engines which may also be fueled with hydrogen.


On the IAA Transportation, MAHLE is displaying its applied sciences for battery electrical automobiles in a tech demonstrator.

The brand new MAHLE SCT (Superior Steady Torque) electrical motor solves a dilemma frequent to many electrical motors: the good discrepancy between steady and peak energy. Whereas earlier electrical motors can solely present their peak energy for a short while after which drop to round 60 to 70 %, the MAHLE SCT electrical motor may be operated repeatedly at greater than 90% of its peak energy.


This implies it might probably run indefinitely at excessive energy and is considerably smaller and lighter than a traditional electrical motor with the identical steady energy. This makes it appropriate to be used in all automobile courses, together with heavy business automobiles.

MAHLE achieved the required technological leap for the SCT electrical motor by utilizing an progressive, built-in oil cooling system.

With the introduction of the brand new electrical motor, MAHLE turns into a full-range provider within the subject of electrical drives. Its choices vary from pedelecs and e-scooters to passenger automobiles and supply vans, in addition to heavy-duty business automobiles, off-road automobiles, and industrial purposes.

On the IAA Transportation, MAHLE can be displaying for the primary time how its programs work collectively in electrical business automobiles. The main focus is on the general drive and thermal administration programs. For the latter, the core parts of the system are the cooling module, air con, high-voltage heater, electrical compressor, battery and digital cooling programs, coolant pump and an oil administration module for temperature management of the electrical motor.

Gasoline cell peripherals. MAHLE historically has robust experience within the areas of air administration, filtration, thermal administration and electronics. The know-how group makes use of this experience in its newest gasoline cell applied sciences. The preparation of the surface air earlier than it’s fed to the gasoline cell is of explicit significance.

MAHLE air filters shield the gasoline cells from particles and dangerous gases with absolute reliability and all through your entire service lifetime of the automobile. A modular idea makes the applying easy and cost-effective. So as to have the ability to work optimally, gasoline cells want humid air. MAHLE’s flat membrane humidifier accomplishes this. It will increase effectivity and protects the cell from drying out.

Dependable humidification can be crucial for sustaining a degree of effectivity and contributes to the lengthy service life of those costly parts.

MAHLE developed the flat membrane humidifier along with different companions. This growth was sponsored by the Federal Ministry for the Economic system and Local weather Safety (BMWK).

So as to stabilize the voltage offered by the gasoline cell throughout all load ranges, the corporate has developed a high-voltage DC/DC converter. It covers excessive outputs of as much as 180 kW, reaches an effectivity of greater than 97% and achieves very excessive energy density.

Hydrogen engines. Along with the gasoline cell, the usage of hydrogen as a combustion gasoline has the potential to make many heavy-duty and off-highway purposes climate-neutral significantly rapidly. Hydrogen engines are suited to excessive load cycles with sudden load steps and deal with warmth, contamination and vibration effectively.

MAHLE will current a brand new energy cell unit for the primary time on the IAA—a system consisting of pistons, piston rings, conrods, pins and, if obligatory, a cylinder liner in addition to a high-pressure impactor for flushing the crankcase. Which means that hydrogen can be utilized extremely effectively and safely in combustion engines with a protracted service life.
