Jan 24, 2012 Blibbler. The electromechanical induction meter operates by counting the revolutions of an aluminium disc which is made to rotate at a speed proportional to the power. The number of revolutions is thus proportional to the energy usage. It consumes a small amount of power, typically around 2 watts. The metallic disc is acted upon by two coils.
User Interaction Count: 1Dec 13, 2014 Eddy Currents are created by a glass disk with strong permanent magnets glued on it. An other aluminum disk is influenced by the currents and starts rotating.

Like most additive processes, DMLS builds the parts from the bottom up, like layers of a cake. It begins with a 3D CAD model, which is sliced into layers roughly 0.001 in. thick. A laser then “draws” each tissue-thin slice of the CAD model on a bed of metal powder, one with the consistency of flour.

Apr 20, 2021 The disc is positioned in the center of the pipe. A rod passes through the disc to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, so it induces a pressure drop, even when open.

Their inner diameter (corresponding to the diameter of the permissible shafts) is up to 80mm. Pancake slip rings work safely at a speed of 0-300 rpm. Due to the use of silver-silver or gold-gold as contact material for rings and brushes, they are very corrosion resistant. Their temperature range is -30 °C to + 80 °C for all versions.
The sensor detects motion by means of a precision metal disc with slots on its periphery generating electronic pulses as the disc rotates past an infra-red light source. These pulses are transmitted to the MSD-800 control unit where the signal is analyzed and the
Feb 24, 2012 As you can see in the figure, there is a thin aluminum disk placed in the gap between the two electromagnets and mounted on a vertical shaft. The eddy currents are induced in the aluminum disk when it cuts the flux produced by both the magnets. As a result of interference of eddy currents and two magnetic fields constitute a deflecting torque in the disk.
the rotating disk, T = brake torque, ω = angular velocity, φ 0 = flux penetrating the rotating disk at rest, D= constant coefficient, depending on pole arrangement, R = reluctance of the electromagnet, β = constant coefficient, γ=10-9/ρ and ρ is the volume resistivity of the disk, the total flux when disk is in motion would be φ φ
