SEMA, short for Segmented ElectroMagnetic Array, is a unique architecture for permanent magnet electric motors and controllers for electric
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.
