The second helical worm gear meshes with the second rotor gear driving the second rotor gear and the second rotatable magnet. The surface areas of the first and second pairs of permanent magnets equals the surface area of the first and second rotatable magnets. | 2012-01-19 |
20120013331 | Method for Producing a Current Metering Device - A method for producing a current metering device with current conductor optionally made of aluminum or aluminum alloy, which has a middle section in the form of a bar and two end sections with flattened areas, and is bent between one end section at a time and the middle section, a magnetic module which has a bushing which holds the current conductor, and two copper or copper alloy sleeves which are applied at least to parts of the end sections of the current conductor. | 2012-01-19 |
