Abstract
The utility model discloses a wound rotor of a motor, which has the advantages of reasonable structure, nondeformable end parts of coils, stability and reliability in operation and low failure rate. The wound rotor of the motor comprises a rotor shaft with supports, the end parts of the coils are connected with the supports through glass fiber ropes, and the end parts of the coils are connected with each other through a packing hoop on the outer wall of the motor.
Description
Technical field
The utility model relates to a kind of motor line winding rotor.
Background technology
The advantage that coiling electric motor has the energy series resistance starting obtains general application in metallurgical lifting industry, but during at high-speed cruising, the coil lashing that often occurs wound rotor owing to reasons such as structures is destroyed normal operation that influences motor and even the phenomenon of burning motor by centrifugal force at existing coiling electric motor.
Summary of the invention
The purpose of this utility model is the deficiency that exists at above-mentioned prior art, and a kind of motor line winding rotor is provided, and this wound rotor is rational in infrastructure, and end winding is indeformable, and stable, reliable, failure rate is low.
The technical solution of the utility model comprises coil, armature spindle, and motor down-lead is arranged with support on the described armature spindle, and its end winding of described coil is connected in support by lashings.
Be that each described end winding interconnects by a wrapping hoop of being located on the outside wall surface; Each described end winding is connected in the corresponding site of support respectively by lashings.
Described support outer surface is arranged with a wrapping layer, and each described end winding is connected in the corresponding site that this is provided with the support of wrapping layer by lashings respectively; The described motor down-lead that is connected to collector ring is connected on the armature spindle by the wrapping layer.
Armature spindle between the respective end of described collector ring and iron core is provided with the wrapping layer, and the described motor down-lead that is connected to collector ring is connected on this armature spindle that is provided with the wrapping layer by the wrapping layer.
Each described end winding is arranged with lashings respectively, and described each end winding that is provided with lashings is connected in the corresponding site of support by lashings respectively or is connected in the corresponding site of the support that is provided with the wrapping layer.
Describedly be respectively equipped with lashings and be connected in support or each end winding of being connected on the support that is provided with wrapping layer interconnects by a wrapping hoop of being located on the outside wall surface by lashings; Described lashings constitutes for the insulation rope yarn, and described wrapping layer and wrapping hoop are respectively insulating barrier and the insulator bracket that insulating tape constitutes.
Described insulation rope yarn is the glass fiber rope, and described insulation belt and insulator bracket are respectively no latitude belt and no latitude strap.
The rotor coil end shape sound construction of wound rotor of the present utility model is reliable, by respectively each end winding (growing the coiler part of core ends) axial and circumferential being fixed, not yielding during operation, the damage that centrifugal force causes end winding in the time of can eliminating the motor high-speed cruising, guarantee the motor safety operation, can extensively be generalized in the rotor structure of motor and engine, effect is obvious.
Description of drawings
Figure is the utility model theory structure schematic diagram.
Embodiment
Now the utility model is described in further detail in conjunction with the accompanying drawings by specification.As shown in the figure, be arranged with support 6 on the armature spindle 2 corresponding to end winding 8, support 6, collector ring 1 and iron core 7 are pressed into respectively and are connected on the armature spindle 2, it is thick with no latitude band support 6 outer surfaces and collector ring 1 to the armature spindle 2 between the respective end of iron core 7 to be carried out wrapped 1mm and 2-3mm respectively, constitutes no latitude belt 3a and 3b at the corresponding site of support 6 and armature spindle 2; Motor down-lead 4 between the respective end of iron core 7 and the collector ring 1 is that the no latitude belt 3c of 2mm is close to colligation and is connected on the armature spindle 2 by thickness, and no latitude belt 3c width is that collector ring 1 is to the distance between the respective end of iron core 7; First to end winding 8 colligations one time by glass fiber rope 5a as the lashings of end winding 8; Adopt separate slot threading mode that each end winding 8 is interconnected with the axial colligation of the corresponding site of support 6 respectively with glass fiber rope 5b again; By forming no latitude strap 9 in the circumferential colligation of each end winding 8 wall with no latitude band, the width of no latitude strap 9 is the length of end winding 8, thickness is 3-4mm, connect by no latitude strap 9 each end winding 8 banding, can effectively prevent the centrifugal distortion of end winding when motor runs up rotor; Motor down-lead 4 is used bolted on connection with collector ring 1; Rotor carries out vacuum paint dipping once with insulating varnish, with quick-drying paint end winding and motor down-lead is partly brushed one deck again, and oven dry is at last handled.
