NOVELTY - The machine has detachable modular stator portions (1) configured to be able to be assembled to form stator. Rotor portions (2) are configured to be assembled to form rotor. One of stator portions and rotor portions is provided with first and second radial components. Other of stator portions and rotor portions is provided with third radial components. Separation gap is provided between and defined by first and second radial components. Third radial component is beatable in separation gap and between first and second radial components. Rotor is movable relative to stator.    USE - Electrical machine such as linear electrical machine, radial-flux and axial-flux rotating electrical machines such as electrical generator such as axial-flux induction generator used for tidal energy harvesting application. Can also be used to wind turbine, wave powered machine and/or electric vehicle.    ADVANTAGE - The gearbox, transmission shaft and mechanical rolling element bearings are not used in the electrical machine. The absence of the components simplifies the system and reduces the cost. The electrical machine does not involve the use of rare earth magnets which increases cost and causes electric shocks. The electrical machine is assembled from the modular stators and modular rotors, so that the ease of manufacturing and maintenance are increased. The manufacturing cost of the electrical machine is reduced. The electrical machine produces the sinusoidal air gap MMF distribution with minimal distortion. The assembled modular stators provide seamless current linkage distribution equivalent to that of electrical machine built with continuous annular stator, so that non-disrupted rotating magnetic field in the air gap is obtained that provides the same peak magnitude and spatial relationship throughout the annular machine. The rotor plate is ironless to reduce corrosion as result of direct exposure to seawater. The rotor plate is weigh less than the permanent magnet mounted rotor so that lighter, lower static friction and lower inertia rotor is obtained for the turbine.
