The Optimal Solution for Electric Motor Simulation

Inductor Efficiency:
CTM Magnetics patented toroidal technology enables highly efficient designs for high frequency applications.

High Frequency Capable:
Engineered to handle frequencies ranging from 0 to 1,000 Hz. This remarkable capability ensures precision and responsiveness in evaluating inductive loads, diverse current levels, and motor controllers, allowing your team to explore the full spectrum of electric motor performance with confidence.

Liquid Cooling:
CTM Magnetics patented liquid cooled technology enables higher thermal efficiency, power density, and performance. With liquid cooling, 97% of the transformer heat is captured by the coolant with only 3% released to ambient. By efficiently dissipating heat, our innovative liquid-cooled solutions not only enhance the performance and longevity of our electric motor simulation products but also provide a competitive advantage in pushing the boundaries of electric motor technology.

Power Density:
Innovative packaging and cooling systems, combined with highly efficient inductors enable unparalleled power density.

Military Grade Shock & Vibration:
CTM liquid cooled inductors have been tested and passed rigorous explosive and extreme shock & vibe military testing. CTM liquid cooled transformers are the optimal choice for electric motor testing applications.
