Abstract

The utility model discloses a disc type motor without iron core, which belongs to the dynamoelectric field, and comprises a rotary shaft, a magnetic pole, a rotor, a front end cap, a rear end cap and a body case, wherein a permanent magnet is respectively fixed on the front end cap and the rear end cap to form magnetic poles on two sides of the rotor, and the rotor is pre-wound, pressed to shape, is placed in a round disc die, and is immersed in a coil winding without iron core formed by congealing DMC-11 plastic liquid, and the rotor is fixed on the rotary shaft. The rotary shaft is fixed on the end caps on a front end and a rear end through a bearing, and the front end cap and the rear end cap are fixed on the body case, since the rotor is made of non-ferromagnetic material, and has no slot effect and has more armature elements and commutator segments, the disc type motor has little torque fluctuation, small rotary inertia and fast response, and meanwhile, the use of non-ferromagnetic material can save a great amount of silicon steel sheets.

Description

The coreless disc type motor
Technical field
The utility model relates to a kind of disc type electric machine, relates in particular to a kind of coreless disc type motor, belongs to the mechanical ﹠ electrical technology field.
Background technology
Along with the raising of automation, mechanization level, market is also more and more higher to the requirement of motor performance, and disc type electric machine obtains the market approval with its efficient height, the superior function stably that turns round, and is used widely; And present high-power disc type electric machine mainly is to adopt the monolateral pole design of groove is arranged, the rotor of this motor makes iron core by silicon steel sheet and the coil in iron core slot is formed, this motor must be used silicon steel sheet, motor in use, there are defectives such as torque fluctuations is big, moment of inertia big, low-response, no longer adapt to the high performance demand for development of dedicated servo motor.
Summary of the invention
The purpose of this utility model provides little, the low inertia of a kind of torque fluctuations, the coreless disc type motor that response is fast at the defective of above-mentioned existence.
The technical solution of the utility model is: a kind of coreless disc type motor, and it comprises rotation axis, permanent magnet, rotor, front and rear cover, casing; Described permanent magnet is separately fixed on front end housing and the rear end cap at rotor both sides formation magnetic pole; Described rotor is that the iron-less core coil winding that the disk mould immerses DMC-11 plastic liquid coagulation forming is put in the good compression moulding of coiling in advance, and rotor is fixed on the rotation axis; Rotation axis by bearing fixing on the end cap of rear and front end; Front and rear cover is fixed on the casing.
The beneficial effects of the utility model are: because rotor is after the good coil windings compression moulding of coiling in advance, again the compression moulding coil windings being put into the disk mould immerses the DMC-11 plastic liquid and solidifies and make, rotor is a nonferromugnetic material, there is not slot effect, torque fluctuations is little, moment of inertia is little, response is fast, simultaneously, the use of nonferromugnetic material can be saved a large amount of silicon steel sheets.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1. rotation axis; 2. permanent magnet; 3. rotor; 4. front end housing; 5. rear end cap; 6. casing.
Embodiment
As shown in fig. 1, a kind of coreless disc type motor, it comprises rotation axis 1, permanent magnet 2, rotor 3, front end housing 4, rear end cap 5, casing 6; Described permanent magnet 2 is separately fixed on front end housing 4 and the rear end cap 5 by epoxy resin, and permanent magnet 2 forms and rotor 3 corresponding magnetic poles in rotor 3 both sides; Described rotor 3 is that the iron-less core coil winding that the disk mould immerses DMC-11 plastic liquid coagulation forming is put in the good compression moulding of coiling in advance, and rotor 3 is fixed on the rotation axis 1; Rotation axis 1 by bearing fixing on front end housing 4 and rear end cap 5; Front end housing 4 and rear end cap 5 are fixed on the casing 6.
