Abstract
The utility model relates to a rotor for an electromotor, which consists of a rotor iron core, a rotor winding and a rotating shaft, wherein the rotor winding is wound at the exterior of the rotor iron core; the rotor iron core is fixed on the rotating shaft; a washer is arranged between the rotor iron core and the rotating shaft; the rotating shaft is made from a cast aluminum alloy material; the rotor iron core is punched and laminated by a plurality of silicon-steel sheets; the depth of each silicon-steel sheet is 0.5mm; a plurality of uniformly-distributed holes are punched at the outer circle of each silicon-steel sheet and used for setting the rotor winding; and H 31-3 epoxy gas spar varnish is coated at the outer circle and the other non-match surfaces of the rotor. The rotor has the beneficial effects of being reasonable in design, simple in structure, light in weight and convenient to install and use.
Description
Technical field
The utility model relates to the motor technology field, is specifically related to a kind of rotator for motor.
Background technology
Motor is the equipment that electric energy is converted to mechanical energy, and in machinery, metallurgy, oil, coal, chemistry, aviation, traffic, agricultural and other various industry, motor is being widely used.Along with industrial automatization improves constantly, need to adopt the element of various control motors as automated system, in the automatic control system of artificial satellite, motor also is indispensable.(in the modern household electrical appliances industry) motor also should use more and more widely in this external national defence, culture and education, medical treatment and the daily life.General motor mainly is made up of two parts: standing part is called stator, and rotating part is called rotor.Also have end cap, fan, case, support, terminal box etc. in addition.The rotor of motor is made up of rotor core, rotor winding and rotating shaft, and rotor design of the prior art is unreasonable, and is many with material, Heavy Weight.
The utility model content
The utility model provides a kind of simple in structure, easy for installation in order to address the above problem, and is few with material, lightweight rotator for motor.
The technical solution of the utility model is as follows:
A kind of rotator for motor is made of rotor core, rotor winding and rotating shaft, it is characterized in that: described rotor winding is wrapped in outside the rotor core, and described rotor core is fixed in the rotating shaft, is provided with packing ring between described rotor core and rotating shaft.
Described rotating shaft is a cast aluminum alloy material.
Described rotor core is punching silicon-steel, is overrided to form, and the thickness of every silicon steel sheet is 0.5 millimeter.
Described silicon steel sheet cylindrical dashes equally distributed hole, is used for being provided with the rotor winding.
Described rotor cylindrical and other non-mating surface spraying H31-3 epoxy air drying varnish.
The beneficial effects of the utility model are: reasonable in design, simple in structure, in light weight, easy to install.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of rotator for motor is made of a rotor core 2, rotor winding (not marking among the figure) and rotating shaft 1, and the rotor winding is wrapped in outside the rotor core 2, the rotor core 2 that the outside is wound with the rotor winding is fixed in the rotating shaft 1, and the centre is added with packing ring 3.Rotating shaft 1 is a cast aluminum alloy material, in light weight, cast easy for installation, in rotor core 2, cause loss in order to reduce rotating magnetic field, require rotor core 2 must magnetic property good, loss is little, and the thick silicon steel sheet of 0.5mm just possesses this advantage, so rotor core 2 adopts silicon steel sheet to build up, dashing at the silicon steel sheet cylindrical has equally distributed hole, being used for settling the rotor winding, at rotor cylindrical and other non-mating surface spraying H31-3 epoxy air drying varnish, is in order to reduce the eddy current loss of rotor core 2 simultaneously.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (5)
