Abstract
The utility model discloses a side magnetic braking device for a motor, which comprises a rotor, a stator, a machine shell and a wind blade which is fixed on a rotor shaft and is positioned at the back of the machine shell. An armature iron which is fixed on the machine shell is arranged between the machine shell and the wind blade, a spring is arranged between the armature iron and the machine shell and compels the movable end of the armature iron to press the wind blade, and an electromagnet which is corresponding to the position of the armature iron is penetrated on the machine shell. In the device, the inner part of the motor is provided with the braking device which can rapidly stop rotating after a switch cuts off electricity.
Description
The utility model relates to the parts of the motor that uses in a kind of motor component, particularly electric tool.
In the prior art, the use of electric tool more and more widely, the power of electric tool is provided by motor, when electric tool when use stops, because action of inertia, electronic meeting is stopped after continuing to rotate a period of time again, and the operative employee can grasp some parts such as drill chuck during this period, it is stopped as early as possible, have on the electric tool of direct-reverse switch at some, the operative employee tend to moment the turn-on reversal switch electric tool is stopped immediately, above-mentioned two kinds of methods of operation were both inconvenient, also relatively more dangerous, also can damage electric tool.
The purpose of this utility model is: a kind of side magnetic braking device of motor is provided, and this device has been installed brake gear at motor internal, can stop operating rapidly after the switch outage.
The technical solution of the utility model is: a kind of side magnetic braking device of motor, comprise rotor, stator, casing, be fixed on the armature spindle and be positioned at the fan blade at casing rear portion, be provided with the armature that is fixed on the casing between described casing and the fan blade, be provided with spring between armature and the casing, spring forces the movable end of armature to press to fan blade, is equipped with the electromagnet corresponding to the position of armature on the casing.
The further technical scheme of the utility model is: a kind of side magnetic braking device of motor, comprise rotor, stator, casing, be fixed on the armature spindle and be positioned at the fan blade at casing rear portion, be provided with the armature that is fixed on the casing between described casing and the fan blade, be provided with spring between armature and the casing, spring forces the movable end of armature to press to fan blade, is equipped with the electromagnet corresponding to the position of armature on the casing; The movable end of described armature is provided with the braking skin towards a side of fan blade.
During use, work as switch connection, electromagnet gets and electric armature is picked up, and makes armature leave fan blade, and motor must be established the beginning by cable and rotates simultaneously; When the switch disconnection, motor is rotated further under action of inertia, and the electromagnet dead electricity is decontroled armature, and armature presses down to fan blade in the effect of spring, and motor is stopped operating immediately.
The utility model has the advantages that:
1. the utility model has been installed armature at casing rear end, and on motor electromagnet is installed, when electric tool uses; electromagnet picks up armature and leaves fan blade, and when electric tool was shut down, the electromagnet dead electricity was decontroled armature; armature presses down to fan blade in the effect of spring, and motor is stopped immediately.
2. the utility model is simple in structure, can electric tool be stopped operating, and is very easy to use.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model.
Wherein: 1 rotor; 2 stators; 3 casings; 4 armature spindles; 5 fan blades; 6 armature; 7 springs; 8 movable ends; 9 electromagnet; 10 braking skins.
Embodiment: as shown in the figure, a kind of side magnetic braking device of motor, comprise rotor [1], stator [2], casing [3], be fixed on the fan blade [5] that casing [3] rear portion was gone up and be positioned to armature spindle [4], be provided with the armature [6] that is fixed on the casing [3] between described casing [3] and the fan blade [5], be provided with spring [7] between armature [6] and the casing [3], spring [7] forces the movable end [8] of armature [6] to press to fan blade [5], is equipped with the electromagnet [9] corresponding to the position of armature [6] on the casing [3]; The movable end [8] of described armature [6] is provided with braking skin [10] towards a side of fan blade [5].During use, work as switch connection, electromagnet [9] must electricly pick up armature [6], makes armature [6] leave fan blade [5], and motor must be established the beginning rotation by cable simultaneously; When the switch disconnection, motor is rotated further under action of inertia, and electromagnet [9] dead electricity is decontroled armature [6], and armature [6] presses down to fan blade [5] in the effect of spring [7], and motor is stopped operating immediately; The utility model is simple in structure, can electric tool be stopped operating, and is very easy to use.
Claims (2)
1. the side magnetic braking device of a motor, comprise rotor [1], stator [2], casing [3], be fixed on the fan blade [5] that casing [3] rear portion was gone up and be positioned to armature spindle [4], it is characterized in that: be provided with the armature [6] that is fixed on the casing [3] between described casing [3] and the fan blade [5], be provided with spring [7] between armature [6] and the casing [3], spring [7] forces the movable end [8] of armature [6] to press to fan blade [5], is equipped with the electromagnet [9] corresponding to the position of armature [6] on the casing [3].
2. the side magnetic braking device of motor according to claim 1 is characterized in that: the movable end [8] of described armature [6] is provided with braking skin [10] towards a side of fan blade [5].
