Background technology

Motor (English: Electricmachinery, is commonly called as " motor ") refers to a kind of calutron realizing electric energy conversion according to the law of electromagnetic induction or transmit.Its Main Function produces driving torque, as the power source of electrical appliance or various machinery.Such as, usually can with motor as its power source in household electrical appliance (as dust catcher).

Existing motor mainly comprises support, stator, rotor, carbon brush.Wherein, carbon brush (Carbonbrush) be also brush, it is the device of transferring energy or signal between standing part and rotating part in motor, it is generally that pure carbon adds coagulating agent and makes, and its form somewhat, as wiping the rubber bar of pencil, top has wire draw, be stuck on metallic support, there is spring handle the inside, and it is pressed in rotating shaft, when electric machine rotation, electric energy is flowed to coil by phase changer; Because its main component is carbon, therefore be called carbon brush.In prior art, electric machine stand is provided with support, first carbon brush is installed in a copper pipe 12, then copper pipe is filled in support, one end of carbon brush is contacted with rotor commutator; Then on copper pipe, weld stator lead 13, the other end of carbon brush is electrically connected with stator coil; Shown in accompanying drawing 1.

But there are the following problems for said structure: (1) needs to adopt welding sequence (being generally electric welding), and make its preparation technology's more complicated, cost is higher; (2) need additionally to adopt the copper pipe coordinated with carbon brush, further increase installation procedure.

Summary of the invention

Goal of the invention of the present utility model is to provide a kind of motor.

To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of motor, comprises support, stator, rotor commutator, carbon brush, and described support is provided with support, and support is provided with the jack coordinated with carbon brush, makes carbon brush be plugged in this jack;

The side of support is provided with inserting-plate hole; Also comprise the metal insert coordinated with described inserting-plate hole, when metal insert is inserted in described inserting-plate hole, described carbon brush is arranged between metal insert and stator, and makes one end of carbon brush and stator realize being electrically connected, the other end and the metal insert of carbon brush realize being electrically connected;

Described metal insert is electrically connected with rotor commutator.

Above, described support, stator, rotor commutator, carbon brush are all prior aries.

In technique scheme, one end of described metal insert realizes being electrically connected by wire and rotor commutator.

In technique scheme, described metal insert is also provided with block tongue, described inserting-plate hole is provided with the bayonet socket of cooperation.Form detachable locking mechanism.Metal insert can be fastened in inserting-plate hole.

In technique scheme, described carbon brush comprises carbon brush body, copper sheet, the wire that is connected to spring between carbon brush body tail end and copper sheet, connects carbon brush body and copper sheet through spring;

When metal insert is inserted in described inserting-plate hole, described carbon brush is arranged between metal insert and stator, and makes the carbon brush body of carbon brush and stator realize being electrically connected, copper sheet and the metal insert of carbon brush realize being electrically connected.

Because technique scheme is used, the utility model compared with prior art has following advantages:

1. the utility model design obtains a kind of new electric machine structure, by being provided with inserting-plate hole on the side of support, described carbon brush is made to be arranged between metal insert and stator by metal insert, namely utilize metal insert to be drawn by the link of carbon brush, recycling metal insert is electrically connected with rotor commutator, i.e. direct metal insert contact conduction, thus eliminate point welding process of the prior art, make the structure of motor more simple, and simplify assemble flow, save production cost;

2. carbon brush can be put in the jack of support by the utility model, eliminates the copper pipe coordinated with carbon brush, and thus structure is more simple, reduces production cost;

3. structure of the present utility model is simple, is easy to realize, and is suitable for applying.
