    en.wikipedia.org/wiki/Harmonized_System

    The process of assigning HS codes is known as "HS Classification". All products can be classified in the HS by using the General Rules for the Interpretation of the Harmonized System ("GRI") that must be applied in strict order. HS codes can be determined by a variety of factors including a product's composition, its form and its function.

  5. Switched reluctance motor - Wikipedia

    en.wikipedia.org/wiki/Switched_reluctance_motor

    The switched reluctance motor (SRM) is a type of reluctance motor. Unlike brushed DC motors , power is delivered to windings in the stator (case) rather than the rotor . This simplifies mechanical design because power does not have to be delivered to the moving rotor, which eliminates the need for a commutator .
