About us

ECM’s patented technology eliminates the need for wire winding and iron laminations used in conventional motors, by embedding copper-etched conductors into a multi-layered printed circuit board to form a stator that works in conjunction with permanent magnets. ECM’s technology platform leverages a proven manufacturing process; following the same wellestablished and proven method utilized in the construction of printed circuit boards (PCB’s), which results in a very reliable and cost-effective production of an entirely new ironless and wireless generator, designed to replace existing convention motion devices, generators, motors and engines.

ECM has expanded on the advantages of axial gap machines to bring superior efficiency, power density and lower costs to variable speed electric motor driven applications.

Axial gap machines have superior attributes in many applications. While permanent magnets and today’s power electronics have been applied to optimize both radial and axial gap machines, winding structures have been constrained by uniform wire diameter and geometry. ECM has perfected a process that optimizes copper geometries and winding patterns that delivers superior efficiency at a reduced cost.

ECM’S licensed patented technology leverages the benefits of the global printed circuit board industry (PCB’s) as they apply to electric motors. With PCB’s, motor winding geometry optimization can occur inside and outside the magnetic field. This simple, cost effective and mature manufacturing process allows for the targeted reduction of resistance and eddy current losses, further increasing efficiency and power density of axial gap motor designs.

To properly optimize motor windings, ECM developed proprietary motor optimization and design software that fundamentally changes the way motors are designed. The optimization code allows users to specify motor characteristics, and uses that input to deliver an optimized stator and magnet design that is immediately ready for production. This significantly reduces design cycle and motor development costs.
