/// 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.
/// SciMo Winding
Distributed winding using rectangular wires:
- over 70% copper filling factor
- very good heat dissipation
- defined location of terminals
- robust and reliable design
/// Conventional Winding
Distributed winding using round wires:
- around 45% copper filling factor
- bad heat dissipation
- manual phase connection
/// Motor Design and 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.
/// Applications
SciMo motors are used in a wide range of applications. Our technology leads to light, efficient and powerful motor designs with highest power densities. The motors are therefore used in a wide range of applications, e.g. Traction motors, e-Booster, electric turbocharger, test bench motors, spindel drives, fly wheels, pumps, compressors.
/// Test bench motors
Our motors are used in advanced test bench applications. The high motor speed in combination with a high torque distribution over the entire speed range are optimal for test bench applications.
/// Motorsport
Our motors are used to power the next generation of Hydrogen Electric Racing cars (Forze Delft), where used in several Hyperloop competitions (1st and 2nd place) and as well as in the Formula Student (World ranking no.1).
/// Aerospace
SciMo motors are very powerful, light and efficient electric motors, an optimal solution for the needs of the electric aviation market. We’re in close cooperation with several companies in the electic aviation sector.
/// Special applications
In many applications there are no suitable motors available on the market. Due to its outstanding performance SciMo can supply motors far beyond what is possible with standard technologies.
