The present invention relates to a winding overhang support for the rotor (1) of an electric generator, comprising at least one ring (4), which absorbs the centrifugal forces of the windings (3) in the winding overhang area.
The present invention further relates to a corresponding method for producing a winding overhang support for a generator.
The invention relates to a winding overhang support (14) for a stator of an electrical machine provided for a single-tooth winding.
The winding overhang of the rotor of an electrical machine is subject to strong centrifugal forces during operation, especially when the machines run at high speed.
By variably adapting the width of the conductor, the space in the winding overhang through which the magnetic flow is directed in the soft magnetic body is utilized.
The invention relates to a hermetically encapsulated compressor, having closed end windings for use in small-type refrigerating installations.
The stator or rotor coil projects from the slot on both sides in a longitudinal direction, forming an end winding.
The invention also relates to methods for producing a stator end winding that is liquid-tight at least in areas.
For this purpose, a section (10) of the respective coolant line (8) extends into the region of the end winding (6).
Their cross-section varies in the end windings, so that the space available is utilised to a high extent and short connection sections are produced.
This can produce a coolant stream in the radial direction from the winding head cap (4), so that the cooling of the winding head is optimized.
The inventive antilock system is purposefully arranged on a front winding head of the electric motor and connected to the winding thereof.
The ventilator(s) (20) is (are) mounted on the cover (2) of the motor chamber or of a coil end chamber (12) and its (their) air outlet openings (21) are directly connected to the latter.
At the slot exit, the conductor cross-section increases and only later, at the coil end (9), halved from only one side at each passage through the coil end.
At least one stator coil and/or rotor coil is arranged in at least one slot of the stator or rotor.
Therefore, a rotor (1) is provided with a winding head cap (4) which has a cylindrical casing.
The header cap may have a fluid port therein coupled to the fluid passageway of the respective stator coil end.
Protection (30, 30') for protecting against the magnetic field produced by the current in the winding head is also necessary.
The coil-end plate (4, 5) has conductor elements (20, 21, 22, 23) to connect it electrically with the conductor rods, the coil-end plate (4, 5) being made up only of insulated conductor elements (20, 21, 22, 23) without a separate support.
The motor has at least one bundle of laminations (3) with slots designed to hold conductor rods.
The aim of the invention is to achieve improved cooling of the winding head in electrical machines of which the rotor is operated at high rotation speeds.
The winding is fixed in the region of its head with a glass-fibre tube (1) passing around each winding rod (2).
Each coil head (6, 7) has a pair of dovetail ribs (8) which are intended to fix the body to the mandrel during the winding.
