    • ‘Thus the rotor half channels entering the stator play the same role as the permanent exit half channel in the stator of the proton motor.’
    • ‘Morganite are manufacturers of heavy industrial and domestic carbon brushes, electric panels, Zesco feeder pillars and fan stators for underground mining.’
    • ‘In addition, the printed circuit board comprises a flat flexible support on which the conductor tracks run from the stator to the rotor.’
    • ‘The stator is composed of two transmembrane proteins, MotA and MotB, that surround the MS ring.’
    • ‘An alternator contains different components which include mainly the rotor and the stator.’
    • ‘The fluids are forced into a small gap between the rotor and the stator where they experience strong shear forces, which causes the molten bitumen to break into minute particles.’
    • ‘The outer-rotor in-wheel motor, however, uses a hollow doughnut construction that locates the rotor outside the stator.’
    • ‘In this scheme, one power stroke of the stator turns the rotor by half a segment.’
    • ‘In general, such products have good punching characteristics, and are used in a variety of applications including small rotors, stators, and small power transformers.’
    • ‘A Mazda alternator is made up of four basic parts: the rotor, the stator, the diode packs, and the voltage regulator.’
    • ‘Inside of the hub is a multi-phase, DC brushless motor, arranged so that the rotor surrounds and rotates around the center-mounted stator.’
    • ‘This pump features a lobed rotor, which rotates within the walls of a stator seated within the pump housing.’
    1. 1.1A row of small stationary aerofoils fixed to the casing of an axial-flow turbine, positioned between the rotors.
