/// Applications

Aviation
Our winding technology is ideally suited for high speed applications. In aerospace most applications operate close to their maximum speed limit. Propellers and gas turbine have there highest output at maximum speed. The hybrid electric “EL-2 Goldfinch” aircraft from Electra Aero is profiting from these unique features. Our SY43.B is connected to a gas turbine, which is acting as generator to provide energy (like a range extender). Starter-generators for gas turbines of aircrafts and helicopter are other suitable applications.
Aerospace Lift & Thrust propeller drives
SciMo’s traditional approach to power propellers for aircrafts, eVTOLS, air taxis and drones is a high speed motor combined with a lightweight gearbox (manufactured by a partner). But by modifying our distributed winding technology, we can now produce windings with ultrashort endwinding, which enables us to build extremely torque dense direct drives. These direct drives produce a high torque at low weight and still allow relatively high speeds of up to 6000 rpm or more. But they can also be optimized for 2000 rpm (or other speeds). The motors come with a integrated inverter and can be water- or air-cooled. At very low speed and high torque the gearbox version has still advantages, as it has lower weight and can be cheaper mass produced.
Starter generators for gas turbine
SciMo has developed starter/generators for applications from 28V to 600 V with speeds from 15.000 rpm to 60.000 rpm. With the high speeds, this is an ideal application for our motor technology.Defense
SciMo electric motors are trusted in the defense industry for their exceptional performance and reliability in mission-critical applications. Despite constraints due to non-disclosure agreements (NDAs), we can highlight why SciMo motors excel in this sector. Our motors offer unmatched power density (up to 17 kW/kg) and efficiencies exceeding 97%, ensuring optimal performance in compact, high-stakes environments. Their robust design withstands extreme conditions, from high temperatures to intense vibrations, making them ideal for demanding defense applications. Additionally, SciMo’s ability to provide highly customized solutions, even for small batch sizes starting at one unit, allows for tailored integration into specialized defense systems.
Compressors
Industrial heat-pumps require high speed compressors, operating at very high speeds at high power levels. SciMo is currently developing a 60.000 rpm, 300 kW motor to directly power a compressor. This project (DiskoHT) is publicly funded.
High efficiency drives
It is a pure waste of money and energy to equip a motor in a 24/7 application with an output power higher than 50 kW with a traditional winding instead of using the SciMo flat wire winding, which offers much higher copper filling factors and much higher efficiency. As soon as you are not grid connected and operate the motor with a frequency inverter (speed variable drive SVD), tell us your requirement at compare, what we have to offer. Depending on the application we can achieve pure motor efficiencies of 98% and inverter+motor efficiencies of 97%.
High dynamics drives
Due to the high power and torque density, SciMo motors offer an extremely lower inertia compared to their torque. This allows dynamics of 500.000 rpm/s even at medium torque levels. Typical applications are high dynamic test bench dynos, motors for endurance burst testing, etc.
Automotive Motorsport
The unique SciMo flat-wire winding technology enables high performance, especially in applications which demand high speed and high power. Due to the thin flat-wires, the frequency dependent losses are massively lower than for example in hairpin windings. Our motors are used in motorsport applications since 2015. In this time these motors have set several track records on the most famous racetracks in the world. Example: Fuel cell power Forze Delft racing team.
Turbo pumps for rocket engines
Liquid and hybrid rockets need cryogenic oxidators (and fuel) to feed their burn? chambers. In this applications high power density and high speed motors are needed, which makes the SciMo motors an ideal choice.
Special Applications
SciMo electric motors have powered groundbreaking projects in cutting-edge applications, showcasing their versatility and high performance. Our motors have been integral to the success of leading Hyperloop teams, demonstrating exceptional power density, lightweight design, and reliability in demanding environments. For the TU Delft Hyperloop Team, SciMo developed a custom SY43.B variant, delivering an impressive 200 kW of power at just 11.5 kg, paired with a inverter weighing only 6 kg. This lightweight, high-performance solution helped the team achieve a remarkable second-place finish in the competition. Similarly, the Munich WARR Team, powered by a SciMo motor, secured victory in the SpaceX Hyperloop Competition in August 2017, following their win in 2016. Their pod reached a maximum speed of 201 mph on a 0.8-mile track, highlighting the motor’s ability to deliver outstanding acceleration and efficiency. SciMo’s tailored solutions, with power densities up to 17 kW/kg and efficiencies exceeding 97%, make our motors the ideal choice for innovative, high-stakes applications requiring precision and durability./// Technology
/// Winding Technology
SciMo has completely redesigned the optimal winding for electric motors, utilizing thin rectangular flat wires that significantly increase the copper density within the motor. Our innovative winding technique enables the use of distributed windings with copper filling factors above 70%, resulting in improved power density and efficiency. Additionally, the material savings in magnets and electric sheet lamination can offset the increased manufacturing costs of the winding process. Overall, our approach to coil winding has the potential to revolutionize the way electric motors are designed and manufactured.
/// Conventional Winding
Distributed winding using round wires:
- around 45% copper filling factor
- bad heat dissipation
- manual phase connection
/// Motor Design & Optimization
At SciMo, we have developed a fully automated, closed-loop process for designing and optimizing the electromagnetic layout of our motors. This process involves detailed simulation of the electric drive system, which allows us to create motors that operate at the highest levels of performance while approaching physical limits.
Our approach involves an iterative process in which we use a fully automated simulation toolchain to achieve a global maximum. We also cross-check the results against test bench measurements in order to refine the simulation process. This continuous improvement of our simulation toolchain enables us to optimize the electromagnetic design of our motors.
- Unique parameter set describes the geometry and materials.
- The geometry is generated in high detail.
- Fully parallelized electromagnetic FEA is performed.
- Generation of a full 3D thermal FEA. Results are simplified to a thermal network of components of interest.
- Output motor data can be used to directly optimized inverter and gearbox design for particular machine layout.
- The simulation results are evaluated and used as feedback for an optimization of the parameter set to start with the next iteration.
The simulation results or output modell fully characterizes the entire drive system, which can be used to apply loadcycles and calculate the expected thermal response. As well, more complex simulations can be performed, for example calculation the maximum dynamics.
The tool chain is regulary benchmarked against test bench runs with our different motors. Deviations between simulations and measurement results are used as input data to optimized the simulation model.
