Case Study: Mieletec FH Bielefeld achieves optimized, energy-efficient, near-silent induction stove designs with COMSOL Multiphysics

Multiphysics Simulation helps Miele to Optimize Induction Stove Designs

Mieletec FH Bielefeld, the joint research lab of Miele & Cie. KG and the University of Applied Sciences Bielefeld, faced the challenge of designing induction cooktops that match or exceed gas stoves in precision and speed while maximizing energy efficiency and eliminating issues like audible noise and pot movement. To tackle these multiphysics problems they used tools from vendor Comsol, specifically COMSOL Multiphysics with the AC/DC and Heat Transfer modules, to model coupled electromagnetic, thermal, and mechanical effects.

Using Comsol’s simulation platform, Mieletec FH Bielefeld optimized coil geometry and drive frequency (raising it to roughly 30 kHz to reduce audible noise), ensured pot stability, and validated designs that matched prototype measurements closely. The simulations cut development experiments by about 80%, delivered near-silent, highly precise induction stoves with over 90% energy transfer to the food, and helped Miele products achieve top energy-efficiency rankings in independent tests.
