CTM was founded in Arizona in 1976 by a Motorola engineer who wanted to design and build line and switching frequency transformers for Motorola. In 1981, the company was purchased by its current ownership.

During the 1980’s and 1990’s CTM Magnetics carved out a growing business in line and switching frequency custom engineered magnetics. Our products used standard components available to anyone during these years; however, our engineering skills, customer service, and quality production team helped build the business to a sustainable level where investment in innovation was possible. Our markets from 1980 through 2004 were medical electronics, professional audio, battery chargers, and some military products.

In 2004, our product development engineers accepted a project to design an inductor on the output of a three phase, 2 kHz variable speed drive delivering 480 V at 1,200 A to a motor. Through a trial and error design method, CTM engineering finally conceived of our first THISS Technology® filter inductor design. The new inductor technology performed brilliantly under the customer’s 1,200 A test, and CTM Magnetics applied for its first patent.

Since 2005, CTM developed substantial IP for THISS Technology® inductors and filters. During this time, CTM internally developed its technology, materials, manufacturing equipment, processes, systems, and controls, while externally building and growing its customer base, markets, and supply chain; these advances allowed CTM to produce its patented technology to a fundamentally new set of markets and customers.

CTM grew by over 300% during this time; it became clear that customers valued the following benefits of our patented inductor and filter technology:

  • 50% reduction in size
  • 50% reduction in weight
  • 50% reduction in power loss
  • 75% reduction in audible noise
  • NO ADDED COST

Our patented THISS Technology® inductors and filters found frequent use in power quality applications on both sides of AC Drives or Inverters, where they were needed to remove harmonic frequencies and voltage spikes from the power line and drive caused by nonlinear loads introduced by power semiconductors.

Today, CTM delivers this large product value to some of the world’s largest companies in Oil and Gas Harvesting, Utility Scale Renewables, VSD Controlled Chillers, Ship and Rail Mass Transportation, Active Filters, and Active Front End AC Drives. We are delivering standard products to our target market space which bring high value with no cost increase. Additionally, we are investing in innovation, developing new filter inductor products for the power semiconductors of tomorrow. CTM is well positioned for growth with our new 5 acre, 60,000 square foot facility to add to our old 2 acre, 20,000 sq. foot site. We continue to invest in our future with people, equipment, and technology so that we can continue to deliver on our value proposition for many years to come.
