SEMA Technology

SEMA, short for Segmented ElectroMagnetic Array, is a unique architecture for permanent magnet electric motors and controllers for electric motor and actuator applications requiring high power density and high efficiency. This electric motor design methodology is based on recent advances in materials, computer aided design, control, and a new appreciation for certain principles of electromotive physics. SEMA motor and controller technology is being developed by Kinetic Art & Technology Corporation and commercialized by Lynx Motion Technology Corporation.

Many applications may benefit from or require a motor drive with high power density and very low torque ripple. These include precision motion control, naval propulsion systems, and acoustically sensitive applications. However, conventionally designed motors often lack the required power density or possess magnetic characteristics that inherently produce low frequency torque oscillations.

In addition to their performance in the above mentioned applications, SEMA motors and generators are capable of producing industry leading efficiencies. SEMAs have been independently tested over 98% efficient without the use of magnetic-levitation or air bearings. In addition, they tend to demonstrate high efficiences over a broad range of torque and speed.

The article An Introduction to SEMATechnology contains a technical overview of SEMA, an overview of current and potential applications and markets, and a summary of technical progress. The PDF document SEMA Features & Benefits provides a detailed description of the features and benefits of the SEMA Technology. The SEMA Redundancy Advantages white paper describes many of the unique advantages of SEMA technology in the way of redundancy. If you would like more detailed information, please contact us.
