Abstract: A method for mounting a magnet of a Hall sensor on a rotor shaft of an electric machine with the aid of an adapter. The magnet is inserted into a receptacle of the adapter in an axial direction in such a way that the magnet is at least partially surrounded by the adapter on the circumferential side in the radial direction. The adapter is plastically deformed to the inside in the radial direction in such a way that the magnet is held in the receptacle. A stamp as well as an electric machine are also provided.

Abstract: A rotor of an electric machine, in particular an electric motor, comprising a rotor body which circumferentially surrounds a shaft, and with a plurality of magnets. Each of the magnets is in each case arranged within a radially extending pocket of the rotor body, and each of the pockets is connected by means of an axially extending slot, each with a radially inner chamber of the rotor body. An electric machine is also provided.

Abstract: A rotor of an electric machine, in particular an electric motor, having a rotor body, which circumferentially surrounds a shaft and includes a first sub-body and a second sub-body. The first sub-body and the second sub-body are joined together in the axial direction by means of an axle which extends in the axial direction and is offset radially to the outside with respect to the shaft. The first sub-body includes an eyelet, within which a socket receiving the axle is arranged, and the second sub-body includes a lug, which receives the axle. An electric machine, in particular an electric motor, is also provided.

Abstract: A telescopic drive contains a base having a securely attached toothed rack running in a first horizontal direction. At least one first carriage is arranged on the base, which is supported on the base such that it moves in the first horizontal direction by a linear guide, and which has a toothed belt drive formed by at least one electric motor and a revolving toothed belt. The toothed belt is driven by the electric motor, is tensioned in the first horizontal direction and is positioned on the toothed rack of the base. By integrating the telescopic drive into an electric-motor-driven cabin inside a three-dimensional shelving matrix of an equipment stand, both a compact construction and movements of a stored item are permitted, with the movements reaching up to or preferably also beyond the extension of an individual storage shelf.

Abstract: A storage and retrieval device, in particular for parallel operation of a high-bay warehouse, contains a device frame, which has frame compartments arranged to form a three-dimensional compartment matrix, and has at least one cab used to hold storage goods. The electromotively driven cab can be moved within the compartment matrix in a vertical direction and/or in a second horizontal direction from each frame compartment. The storage and retrieval device advantageously realizes fast access because of the movability of the cab within a device frame of the storage and retrieval device in a vertical direction and/or in a second horizontal direction and realizes a high handling rate of storage goods in the operation of a high-bay warehouse because of the parallel operation of a plurality of cabs.

Abstract: An electrical machine, in particular a synchronous reluctance motor, having a rotor having a number of similar permanent magnets, each of which is disposed in each case in an associated pocket of the rotor. Permanent magnets adjacent in a tangential direction can be installed only in one position in the respective pocket, in which the magnetization directions is rotated by 180° with respect to a radial straight line associated with the respective permanent magnet. A rotor of an electrical machine is also provided.

Abstract: An apparatus and a method actuate a frequency converter of an electric machine having a safety function, in particular a safe-torque-off (STO) function. Wherein, by a preferably clocked converter circuit, an electrically isolated output voltage is generated from an input voltage, from which output voltage a control signal is generated for the frequency converter for the operation thereof in accordance with standards and for triggering the safety function. An actuation signal is generated for a semiconductor switch which is periodically connected to the input voltage, and the output voltage is limited when the output voltage exceeds a switching threshold.
