Utility model content
The purpose of this utility model is to provide a kind of plastic package brushless direct current motor, is intended to solve the problem adopting the equipment of plastic package brushless direct current motor or the electromagnetic interference existing for system to exceed standard.
The utility model is achieved in that a kind of plastic package brushless direct current motor, and it has end cap and is built-in with drived control plate, and described drived control plate is for controlling the running of plastic package brushless direct current motor;
Described plastic package brushless direct current motor also comprises a capacitor, described capacitor is connected between the power ground of described end cap and described drived control plate, and the electromagnetic interference that described capacitor is used for producing when controlling plastic package brushless direct current motor running to described drived control plate carries out filtering process.
Further, described capacitor can be specifically safety electric capacity.
The utility model embodiment still provides a kind of control panel comprising above-mentioned plastic package brushless direct current motor.
In the utility model, by adopting capacitor in plastic package brushless direct current motor, capacitor is arranged between the end cap of plastic package brushless direct current motor and the power ground of drived control plate, the electromagnetic interference being controlled to produce when plastic package brushless direct current motor operates by couple capacitors drived control plate carries out filtering process, thus effectively can reduce electromagnetic interference, and be conducive to promoting the employing equipment of plastic package brushless direct current motor or the Electro Magnetic Compatibility of system, solve the problem adopting the equipment of plastic package brushless direct current motor or the electromagnetic interference existing for system to exceed standard.
Accompanying drawing explanation
Fig. 1 is the structural representation of the plastic package brushless direct current motor that the utility model embodiment provides;
Fig. 2 is the internal circuit principle schematic of the plastic package brushless direct current motor that the utility model embodiment provides.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the plastic package brushless direct current motor that the utility model embodiment provides has end cap 100 and is built-in with drived control plate 200, and drived control plate 200 is for controlling the running of plastic package brushless direct current motor.Drived control plate 200 is provided with the governor circuit controlled that operates is carried out to plastic package brushless direct current motor.
Plastic package brushless direct current motor also comprises a capacitor 300, capacitor 300 is connected between the power ground GND of end cap 100 and drived control plate 200, and the electromagnetic interference produced capacitor 300 is for controlling plastic package brushless direct current motor running during to drived control plate 200 carries out filtering process.
Plastic package brushless direct current motor shown in corresponding diagram 1, Fig. 2 shows its circuit theory schematic diagram, wherein, the earth terminal of the governor circuit 201 on drived control plate 200 connects power supply ground, so capacitor 300 is just equivalent to be connected between the earth terminal of end cap 100 and governor circuit 201, because governor circuit 201 is for controlling the running of plastic package brushless direct current motor, so governor circuit 201 also connects the winding coil 400 in plastic package brushless direct current motor.
In the utility model embodiment, above-mentioned capacitor 300 can be installed on the printed circuit board (PCB) of drived control plate 200, also the outside of drived control plate 200 can be arranged at, in addition, the installation of capacitor 300 arranges and is not limited in above-mentioned two kinds of modes, as long as can ensure the plastic package brushless direct current motor that all applicable the utility model embodiment of any installation set-up mode between the power ground that capacitor 300 is connected to end cap 100 and drived control plate 200 provides.
Further, capacitor 300 can be specifically safety electric capacity, by adopting safety electric capacity to carry out filtering to the electromagnetic interference that drived control plate 200 produces, can electromagnetic interference be effectively reduced, thus the equipment of employing plastic package brushless direct current motor or the Electro Magnetic Compatibility of system are got a promotion.
Therefore, in the utility model embodiment, by adopting capacitor 300 in plastic package brushless direct current motor, capacitor 300 is arranged between the end cap 100 of plastic package brushless direct current motor and the power ground GND of drived control plate 200, the electromagnetic interference being controlled to produce when plastic package brushless direct current motor operates by capacitor 300 pairs of drived control plates 200 carries out filtering process, thus effectively can reduce electromagnetic interference, and be conducive to promoting the employing equipment of plastic package brushless direct current motor or the Electro Magnetic Compatibility of system, solve the problem adopting the equipment of plastic package brushless direct current motor or the electromagnetic interference existing for system to exceed standard.
Because above-mentioned plastic package brushless direct current motor can make the Electro Magnetic Compatibility of equipment or system get a promotion, be convenient to be applied in various control panel, so the utility model embodiment still provides a kind of control panel comprising above-mentioned plastic package brushless direct current motor.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
