A drive wheel () wherein the drive wheel () is formed by an injection-molding process, and has a longitudinal axis (), having a hub region () with a hub opening (), having an annular toothed-rim region () with a radially outwardly projecting toothing (), having a substantially disk-like intermediate region () which is arranged radially between the hub region () and the toothed-rim region (), wherein the drive wheel () has two bearing points (), arranged concentrically with the longitudinal axis (), for radial mounting and two bearing points (), for axial mounting, and wherein the hub region () has an extension () that protrudes from the plane of the intermediate region () in the direction of the longitudinal axis ().

Drive wheel for a transmission drive device, and transmission drive device

A rotor of an electrical machine has at least one hollow-cylindrical, first permanent magnet with axial bearing surfaces that interact with at least one retaining element and with a sensor magnet assembly, and the first permanent magnet and the sensor magnet assembly are retained axially between two retaining elements.

Rotor and an electrical machine comprising such a rotor

The present invention relates to an electrical machine having a rotor, a stator, and a permanent magnet located on the rotor. The permanent magnet is embodied essentially as a hollow cylinder with axial and/or radial contact faces and is secured to the rotor at the axial and/or radial contact faces by means of retaining elements; the permanent magnet is elastically supported in the axial direction (X-X) and/or the radial direction of the rotor by means of the retaining elements.

Electric machine comprising a permanent magnet

The rotor () of an electrical machine (), having at least one permanent magnet (), which is embodied as a hollow cylinder () and which has axial contact faces () that cooperate with corresponding axial clamping faces () of at least one retaining element (), with which element the permanent magnet () is secured to the rotor (), in which at least one of the clamping faces () has a knurling () extending in the radial direction.

Rotor of an electrical machine

An electrical machine including at least one sensor, a transducer wheel at which the sensor axially picks up a signal, an end face of the sensor being adjacent to an annular face on one face end of the transducer wheel, a shaft, on which the transducer wheel is axially displaceably secured, a fixed bearing, and a loose bearing, in which bearings the shaft is supported, and a housing. At least one stop on the machine having at least one stop face that points in the direction of the fixed bearing and has at least one stop face on the transducer wheel, the stop faces being oriented toward one another and axially facing one another. Viewed in the direction of the transducer wheel, the stop faces are designed relative to one another such that the two diametrically opposed active surfaces of the sensor and of the transducer wheel barely do not touch. As a result, the power deviation of the complete electrical machine is reduced due to the minimization of the required axial spacing tolerances between the sensor and the transducer wheel.

Electrical machine and method for adjusting an axial spacing of the electrical machine

An electrical machine, in particular a direct current motor for vehicles, has a multi-pole stator which has an annular pole housing () and a plurality of magnets () that are located on the inside face of the pole housing (). The electrical machine further includes a magnet splinter guard (), which shields the magnets () inward in the radial direction toward the rotor, in which the magnet splinter guard () is formed from a rectangular blank, has an overlapping region (), extending in the circumferential direction over the axial length of the magnet splinter guard (). On each of the ends () of the magnet splinter guard () located in the axial direction, a respective centering ring () is located, for centering the magnet splinter guard ().
