Abstract
The utility model relates to a kind of plastic package brushless direct current motor, comprise front end housing, rear end cap, rotating shaft, plastic shell, stators and rotators between described front end housing and described rear end cap, also be provided with the variable frequency control plate for changing electric current and voltage in plastic casing inside, the 310V pulsation sine DC electricity that power model on air-conditioning control panel can pass over by variable frequency control plate becomes the alternating current of 220V, meets the voltage requirements of motor, improve the overall transformation efficiency of motor, energy-conserving and environment-protective.
Description
Technical field
The utility model belongs to machine field, is specifically related to a kind of plastic package brushless direct current motor.
Background technology
Plastic packaging motor adopts plastic package technology that the engineering plastics such as the stator core of motor, winding are carried out overall package, can cancel traditional motor stator insulated treatment process and the metal chassis of common electric machine, this motor uses widely at the white goods industry such as washing machine, air-conditioning.But traditional plastic packaging motor electric energy conversion efficiency is low, and noise is also larger.
Utility model content
Low in order to solve traditional plastic packaging motor electric energy conversion efficiency, the defect that noise is large, it is high that the utility model provides a kind of electric energy conversion rate, the DC brushless motor that noise is little.
In order to address this problem, the technical solution adopted in the utility model is: a kind of plastic package brushless direct current motor, comprise front end housing, rear end cap, rotating shaft, plastic shell, is arranged on the stators and rotators between described front end housing and described rear end cap, is also provided with the variable frequency control plate for changing electric current and voltage in described plastic casing inside.The 310V pulsation sine DC electricity that power model on air-conditioning control panel can pass over by variable frequency control plate becomes the alternating current of 220V, thus improves the overall transformation efficiency of motor.Preferably, described stator comprises stator core, Insulating frame and winding, and described stator and described front end housing pass through injection mo(u)lding.The capsulation material that injection mo(u)lding adopts is special thermoset glass fibre unsaturated polyester (UP) bulk plastics, and the motor after plastic packaging can reduce its operating noise, improve its security performance and unfailing performance.
Preferably, described rotor comprises rotor core and permanent magnet, and described permanent magnet adopts ferrite magnetic shoe to make.This magnetic shoe coercive force is high, and anti-degaussing ability is strong, but the rotor self utilizing its high characteristic rectifying stupid ability to make produces magnetic field, less excitation loss rate, improves the efficiency of motor.
Preferably, described variable frequency control plate is also provided with lead pin, lead pin is arranged on variable frequency control plate, positions welding when mounted by lead pin to variable frequency control plate.
The beneficial effects of the utility model are: the plastic package structure that plastic package brushless direct current motor adopts can reduce operating noise, improve security performance and unfailing performance, in the utility model, plastic casing inside is provided with the variable frequency control plate for changing electric current and voltage in addition, the 310V pulsation sine DC electricity that power model on air-conditioning control panel can pass over by variable frequency control plate becomes the alternating current of 220V, improve the overall transformation efficiency of motor, energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1 is effect structure figure of the present utility model.
Wherein 1 is front end housing, and 2 is rear end cap, and 3 is rotating shaft, and 4 is plastic shell, and 5 is stator, and 6 is rotor, and 7 is variable frequency control plate, and 8 is lead pin.
Embodiment
Further understanding to do the utility model, coordinating accompanying drawing to be further described below:
As shown in Figure 1, a kind of plastic package brushless direct current motor, comprises front end housing 1, rear end cap 2, rotating shaft 3, plastic shell 4, the stator 5 between front end housing 1 and described rear end cap 2 and rotor 6, and stator comprises stator core, Insulating frame and winding (not marking in figure).Stator 5 and front end housing 1 pass through injection mo(u)lding.Stator 5 is on stator core, mix the Insulating frame taken, and then by stator winding around Insulating frame on the surface, finally winding on stator is carried out injection mo(u)lding by the star-like martingale of three-phase together with front end housing mould and plastics.
Rotor 6 comprises rotor core and permanent magnet (not marking in figure), described permanent magnet adopts ferrite magnetic shoe to make, this magnetic shoe has the features such as high, the anti-degaussing ability of strong stupid ability is strong, but self produces magnetic field after making permanent magnet, compare alternating current machine, less excitation loss, improves motor working efficiency.
Plastic casing inside is provided with the variable frequency control plate 7 for changing electric current and voltage, variable frequency control plate 7 is connected with the stator 5 after injection moulding, variable frequency control plate 7 is also provided with lead pin 8, lead pin 8 can be utilized to be fixedly welded on plastic casing inside to by variable frequency control plate 7.
Stator 5 and front end housing 1 plastic packaging are in plastic shell 4, and it is inner that variable frequency control plate 8 is welded to plastic shell 4, and in the rotating shaft of rotor 6, cover has bearing, and is connected with plastic shell 4 by rear end cap 2.During assembling, first front end housing 1 and stator 5 are put into plastic package die inner position in the lump and fix, put into by plastic package die on injection moulding machine, moulding compound being put into injection moulding machine, to carry out plastic packaging shaping, makes the plastic shell 4 with stator 5 and front end housing 1.Then the rotor 6 with bearing is put into injection casing 4, and variable frequency control plate 7 is put into plastic shell 4 and positions welding by lead pin 8, finally rear end cap 2 and the plastic shell 4 containing rotor 6, variable frequency control plate 8 are carried out being assembled into complete machine.This plastic packaging motor reduces operating noise, improves the overall transformation efficiency of motor, energy-conserving and environment-protective.
More than show and describe general principle of the present utility model, 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; the just principle of the present utility model described in above-described embodiment and specification; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications; these changes and improvements all fall in claimed scope of the present utility model, and the protection range that the utility model requires is defined by appending claims and equivalent thereof.
