Abstract: An electrolytic cell, a method for manufacturing the cell, and a method of operating same. The electrolytic cell has at least two bipolar plates, at least one fluid inflow and outflow, as well as at least one laminated core arranged between the at least two bipolar plates. The laminated core is constructed from laminations which are stacked one on top of the other. At least two laminations have recesses which are designed to extend through the entire thickness of the respective lamination. The at least two laminations are arranged one on top of the other in such a way that recesses in adjacent laminations overlap partially, but not completely, as a result of which ducts, which are continuous in the direction of the plane of the lamination, are formed.

Abstract: A converter that feeds an electric drive in an electric vehicle is used to transmit energy to the vehicle without contact using resonant operation for inductive transmission of energy. The leakage inductance of the transformer is resonantly adjusted by a serial capacitor. The load current is then switched at zero-crossing.

Abstract: Power is supplied to excitation windings in order to generate magnetic fields, preferably for activating superconducting coils. An AC transformer is used, and triggering of the coil is performed via a rectifier having little power loss. Preferably, a two-way rectifier using a freewheeling circuit is utilized in the associate device, thus preventing losses when power is supplied and especially when the power is discharged.

Abstract: The invention relates to a potting method and a device (100) for potting an excitation circuit that is arranged inside a rotor body. Said excitation circuit has a circuit board (102, 103) having contacts (103, 103?) on the edge of said circuit board (102, 103), the contacts (103, 103?) being arranged in a tolerance zone (109) around a cylindrical peripheral surface (110) that is concentric to the rotor body. The excitation circuit is located inside a potting zone (101) which is sealed in a liquid-tight manner by a toroidal elastic ring (111) in such a manner that surfaces of the contacts (103, 103?) lying within the tolerance zone (109) are at the same time in contact with the toroidal elastic ring (112).

Abstract: A magnet wheel and a stator winding which are necessary for an excitation device are included in a synchronous machine. Energy is transferred to the magnet wheel through inductivity, preferably, energy to a super-conductive coil, by the excitation device. Protection against the magnetic field produced by the current in the winding head is provided in the form of a specific system which is used to reduce the corruptions of the interfering fields of stator and rotor winding.

Abstract: The invention relates to a retaining device (100) for electrical components (103) of an excitation circuit arranged inside a rotor body (101) and to a rotor comprising said retaining device (100). The retaining device (100) extends on the interior of the rotor body (101) and is adapted to the rotor body (101) on its radially outer side in a form-fitting manner. On its radially inner side, the retaining device (100) comprises recesses or flattened sections (102) for receiving the electrical components (103) in a form-fit manner.
