    摘要: A power generator that operates at a reduced keybar voltages and currents, flange currents, and keybar voltage differentials includes a keybar shield that reduces the amount of magnetic flux coupling into a keybar of multiple keybars during operation of the generator. By reducing the amount of coupled flux, the keybar shield reduces a keybar voltage and a keybar current in a keybar, reduces keybar current flowing into a flange, and reduces a voltage differential between voltages induced by the flux in the multiple keybars.

    摘要: A method for estimating rotor shaft velocity includes adding two counter rotating signal components to a fundamental motor control signal to provide a combined control signal; sensing at least one motor phase signal; determining an extracted portion of the motor phase signal representative of the two counter rotating signal components; and using the extracted portion to estimate rotor shaft velocity. The step of adding two counter rotating signal components may include either adding a single phase signal in a reference frame synchronous to the fundamental motor control signal or adding two separate signals.

    摘要: A human-powered generator system for electric watercycles with a control means whereby the perceived mechanical properties of the pedal mechanism and electric pedal-powered generator are adjustable by the operator. The invention provides a means whereby the rotational inertia and damping of the input pedal mechanism, including generator, as perceived by the operator can be increased or decreased as desired. The control means with further properties such that the input pedal mechanism as perceived by the operator can be made to mimic that of bicycle; i.e., with large inertia when pedaling in the forward direction, a very low inertia when pedaling in the reverse direction, and a freewheeling clutch mechanism whereby the large inertia is disengaged when not pedaling in the forward direction with a forward torque. The control means further enable the electric watercycle to be perceived as coasting through the water when the operator takes a momentary break from pedaling, much like that of a bicycle coasting.
