Power Transformer: Finite Element Based Design
FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization
Problems associated with power transformers are not only related to design matters such as satisfying basic characteristics, but also includes many issues related to testing and maintenance such as magnetic flux leakage accompanying increased capacity causes localized stray loss in the tank. A coil’s dielectric strength needs to be verified by a local maximum electric field. The part arrangement between core and coil or magnetic flux distribution also has an effect on vibration caused by the electromagnetic force.
FEA (Finite Element) based Design and simulation enables us to visualization of the phenomena and ease in moving forward with analyzing causes. It also makes possible quantitative evaluations of magnetic saturation, eddy current, induced voltage, stray loss, iron loss, magnetostrictive force, power, efficiency, temperature and the electric fields noise where measurement is difficult.
Multiphysics Simulation: Electromagnetic–Structural Dynamics–Fluid–Acoustics
By coupling the electromagnetic field solution with other solvers, we examine coupled physics phenomena and achieve the highest fidelity solution to eliminate reliability problems and design safe and effective products. Combination of advanced FEA and computational tools lead to special platform that let us to manages the data transfer between physics solutions and handles solver interactions, so we can set up and analyze complex coupled-physics behaviors such as:
- Electromagnetic–Structural
- Electromagnetic–Structural with stress and strain coupling effects on on magnetic properties
- Electromagnetic–Fluids interaction with coupling of CFD and Electromagnetic Solvers
- Electromagnetic–Structural–Fluids
- Electromagnetic–Structural Dynamics–Acoustics
Noise, Vibration & Harshness – NVH for Electric Motors
To optimize for NVH, our engineers use the forces from the EM analysis to perform advanced vibro-acoustic simulations. The forces are mapped to evaluate the structural dynamics response of the motor.
Modal and harmonic stress coupling responses are important for simulating the NVH of an electric motor and for proper vibro-acoustic design of electric vehicles (EVs). The harmonic analyses generate absolute magnitudes of vibrations and waterfall diagrams to get a complete picture of the motor’s acoustic profile.
