Industrial & Commercial

No commercially available electric motor or generator is better suited toward variable frequency, variable speed/high speed applications than LE's permanent magnet machines. Efficiency advances in electric motors and generators previously sought through less suitable technologies are made possible by leveraging the low losses of amorphous iron. According to The Appliance Standards Awareness Project, "Electric motors account for approximately 60% of electricity consumption in industrial applications. The efficiency of electric motors can be improved by decreasing resistance to current flow; reducing core losses in the steel components; decreasing losses caused by motor bearings; and using a better cooling system."

Why choose permanent magnet, brushless electric machines?
LE's patented technology has overcome the intrinsic disadvantage of lower magnetic operating induction typically found in amorphous iron. As a result, we solved the problem of cost-effectively processing amorphous iron into a machine stator. LE's technology delivers:

• ultra-low core loss. Our 90% reduction in electromagnetic core losses equal higher power density.


• frequency-enabled, translating to more power. LE machines provide triple the increase in frequency, ultimately resulting in double the torque density without sacrificing speed.


• power-dense machines. Our three-fold increase in frequency ultimately results in double the torque density, resulting in double the power density.


• smaller machine sizes. LE machines provide increased power density (power/weight, power/volume) and are about one-third the size and weight of other, more traditional motors.The result? Smaller machines, less active material, lighter weight and drop-in ease of use.


• high efficiencies. At 95% efficiency, LE machines exceed full-load efficiencies under NEMA standards and The Energy Independence and Security Act of 2007.


• robust design, reliable, long lasting and durable. One moving element, longer life cycles, higher reliability.


• less demanding cooling constraints. TENV, TELC or TEFC; standard motor rating is IP65. LE can provide up to IP67 rating.


• voltage output choices. Easy modification of series/parallel coil connections.

Typical applications for LE products include:
  -HEV / EV traction
  -power generation, mobile power systems
  -industrial motors, commercial HVAC, pumps
  -high speed/frequency power systems
  -mobile power/on-board power applications
