Abstract

The invention relates to electrical engineering. The purpose of the invention is to increase reliability in operation. The stator core 1 is installed in the housing 2. At the locations of the installation of the longitudinal 6; 3, supporting elements 4 are attached to the housing. At the ends of the beams 3, using bolts 7, are attached fixed end rings 5 for mounting the bearing shields. The longitudinal beams 3 are provided with support surfaces 6 for installing shock absorbing blocks, by means of which the electric machine is uniformly secured in the vehicle frame, whereby the static and dynamic forces are evenly distributed between the structural elements of the machine and the specified frame. The invention makes it possible to reduce the level of vibration and to reduce transportation. 2 Il. with ts (ls

The invention relates to high power electric machines, assigned to w si operation in autonomous vehicles, where there is no EOT condition for the installation of foundations and are limited by gabrgts,

The installation of an electrical machine (without foundation) determines its implementation with shield panels, which requires a strong case of an elaptic machine for mounting underhead panels, However, this leads to increased outer diameter and cannot be done because of the transport of 1 machine to the site installation.

The purpose of the inventor is to increase the reliability.

it should be tied in parts. The absence of a solid hull and its replacement by evenly spaced beams significantly reduce eddy current losses in the hull area above the frontal parts, which increases the efficiency of the machine. In addition, it is easier to access the Frontal Parts directly, which, in the case of using liquid cooling in the stator winding day, significantly improves the maintainability.

Claims (1)

Invention Formula Stato: P of an electric vehicle of a vehicle, containing a laminated core installed in a housing, longitudinal beams, joining and extending the force of the beams 3, the strut to the end support rings. Nachal for installation, shock absorbing blocks of blooms with the help of a small pox (the main thing is "fastening the sprue slit in the vehicle's 9 framework" Electr-iche machine evenly fitting in the vehicle body and static to the dynamic conditions are evenly distributed between the structural elements of the electrical and vehicle frame. 50 55 characterized in that, in order to increase reliability, the longitudinal banks are installed on supporting elements connected to the body and are evenly placed around it, and the beams are connected to the end rings by means of detachable nodes, while the longitudinal beams are made vehicle frame. 0 0 five The proposed design of an electric machine has increased rigidity and strength of the stator housing, reduced vibration level of the entire machine, this reduces the metal consumption and simplifies transportation. The longitudinal beams are the main elements that connect the stator core with the rotor of the ms rotor using bearing shields installed in the end bearing rings in one-piece design. The supporting elements serve to fasten the longitudinal beams, for example, by means of disassembling nodes, i.e. beams become removable structural elements. This reduces the outer transport dimension of the stator. The presence of a detachable connection between the longitudinal beams, end rings and the stator core body allows after testing at the factory it should be tied in parts. The absence of a solid hull and its replacement by evenly spaced beams significantly reduce eddy current losses in the hull area above the frontal parts, which increases the efficiency of the machine. In addition, it is easier to access the Frontal Parts directly, which, in the case of using liquid cooling in the stator winding day, significantly improves the maintainability. Invention Formula Stato: P electric vehicle of the vehicle, containing a laminated core installed in the housing, longitudinal beams, attached to the end support rings. characterized in that, in order to increase reliability, the longitudinal banks are installed on supporting elements connected to the body and are evenly placed around it, and the beams are connected to the end rings by means of detachable nodes, while the longitudinal beams are made vehicle frame.
