Problems solved by technology

In addition, magnet elements attract metallic impurities from the environment and thus lead to contamination
In addition, high costs arise in the manufacture of the holding element and the centering bore of the rotor shaft
Finally, the axial end positions of the magnet elements and their coaxiality with respect to the rotor axis have relatively large tolerances

Embodiment Construction

[0027] exist figure 2 The end of the rotor shaft 16 remote from the rotor in an electronically commutated motor is shown in . This end of the rotor shaft 16 carries a signal transmitter 24 . The signal transmitter comprises a magnet element 26 which is arranged in the interior of a holding element 28 and is fastened to the rotor shaft 16 in a rotationally fixed manner by means of the holding element 28 .

[0028] For this purpose, the holding element 28 is cup-shaped and has a hollow-cylindrical shaft 40 which is closed at its end by a base 42 . The holding element 28 is pushed with its open end onto the rotor shaft 16 such that a section of the rod 40 and a section of the rotor shaft 16 overlap each other. The base 42 also covers the end face of the magnet element 26 facing away from the rotor shaft 16 . The support site for the magnet element 26 can be configured at the bottom 42 so that, if a magnet element is provided, the cross-section of the adhesive gap between the ...

Abstract

The invention relates to an electronically commutated electric motor (10), in particular an electronically commutated electric motor. In order to detect the angle or rotational speed of rotation accomplished by a rotor shaft (16) of an electric motor (10), the rotor shaft (16) is equipped with a signal transmitter (24) of a sensor device. The signal transmitter has a magnet element (26) which is fixed to the rotor shaft (16) by means of a retaining element (28). The invention relates to a clamping body (46) which is arranged on the rotor shaft (16) in a force-transmitting manner and onto which the holding element (28) is pressed.

Description

technical field [0001] The invention relates to an electronically commutated electric motor according to the features of the preamble of claim 1 , an electronically skid-controllable brake system according to the features of the preamble of claim 11 and a motor according to the features of the preamble of claim 12 . A method for fabricating electronically commutated electric motors is featured. Background technique [0002] Electronically commutated electric motors are used, for example, as drive units in electronically slip-controllable brake systems of motor vehicles to drive pressure generators in the context of brake pressure regulation. In this case, the electrical control of the electric motor is carried out by the electronic control unit of the brake system in a manner adapted to the requirements. In the case of electrical actuation, the pressure generator supplies pressure medium in the brake circuit. A brake pressure then builds up in the connected wheel brakes pr...
