A pendant sprinkler head includes a sprinkler body formed with a central orifice, and a sealing member positioned within the orifice and in sealing engagement with the inlet. The bobbins are formed by a insulating material in which are embedded electrical connectors that have terminal ends that afford connection to the coil windings and to an external connection for either deriving electrical power in the case the machine operates as a generator or receiving power in the event the device operates as a motor. A cleaning brush having a plurality of bristles, at least some of which are electrically conductive, engages the transfer roller. The first capacitor reduces a ripple component of the carry signal of the present stage which activates the next stage.
