High demand for cobalt-iron alloys: Low-emission flying in the uplift
Stator stacks made of electrical steel and VACODUR 49 for a synchronous machine with the same torque.
The CoFe material VACODUR®49 fully exploits its advantages in turboelectric hybrid systems: better flux control can typically increase the power density, one of the most important properties of synchronous machines, by 30 %. This allows the torque and maximum power (constant size/weight) to be increased or the required size and weight (constant torque/power) to be minimized.
VACODUR is characterized by a high magnetic saturation of up to 2.3 T in combination with low coercivity. Adapted annealing temperatures meet the demanding strength requirements for high speeds. The wide range of alloys and laminations available is widely used in new projects for hybrid or all-electric aircraft, both in the generator and in the propulsion motor. This enables designers to achieve the optimum balance between torque and weight.
"All major aircraft engine manufacturers are involved in the hybridization of short- and medium-haul aircraft. The aim is not only to reduce fuel consumption, but also to reduce the cost of noise protection measures and bypass flight bans by significantly reducing noise during take-off and landing," says Dr. Robert Brand, Application Specialist at VAC.

Thermoelectric materials enable reduction of CO2 emissions
Energy generation from waste heat
In industry, transport and households a huge amount of unused energy is generated in the form of waste heat. This potential could be used as a sustainable energy resource using thermoelectric generators (TEG). The thermal energy could be converted directly into electrical power, which makes an important contribution to energy recovery and thus to reducing of CO2 emissions. The…

Ultra-compact filter chokes support alternative drive concepts: Driving into the …
The European Commission's CO2 limit values represent a challenge for the automotive industry that cannot be met with conventional combustion engines. Fast and cost-efficient hybridization is required to achieve these targets. This also requires new electrical components such as inverters and DC-DC converters. One of the major challenges in inverters is the very limited space available for which the very compact filter chokes are an advantageous solution.
The chokes constructed with…
