Abstract
The utility model provides a novel direct current motor with permanent magnetism, which comprises a rotor, a stator, etc. Commutators are arranged on the stator in a circle, the tail parts of the commutators are connected with an armature winding, a rotary disc with carbon brushes is installed on a rotary shaft of the rotor, and the edge of the rotary disc is provided with even pairs of carbon brushes. Thus, when the rotor rotates, the rotary disc with carbon brushes is driven to rotate, and thus the carbon brushes are driven to move on the commutators. The commutators are installed on the stator to act the two functions of power and electricity generation in the motor. In the course of power, the sent and received electric energy and power supply are formed to a loop, the input power supply power is effectively fed back for obtaining the purposes of high efficiency and energy saving.
Description
Technical field:
The utility model relates to a kind of improvement of motor, and a kind of novel permanent magnetic direct current machine especially is provided.
Background technology:
Traditional dc motor structure comprises rotor, stator etc., and the rotating shaft of rotor is as the output shaft output mechanical energy, and its excitation winding is contained on the casing, and commutator is installed on the main shaft of rotor one end, the commutation operation.Its structure is complicated, and efficient is not high.
Summary of the invention:
The purpose of this utility model is a kind of novel permanent magnetic direct current machine of design.
The technical solution of the utility model is: a kind of novel permanent magnetic direct current machine, include rotor, stator, it is characterized in that commutator is rounded is arranged on the stator, the afterbody of commutator is connected with armature winding, a carbon brush rotating disk is installed in the rotating shaft of rotor, the edge of this rotating disk has the carbon brush of even-even, and carbon brush closely contacts with commutator.During rotor rotation, drive the carbon brush dial rotation like this, on commutator, move thereby drive carbon brush.In this motor, commutator is installed on the stator, plays work done, two effects of generating, in the process of work done electric energy and the power supply of sending out is formed the loop, will import power supply energy and effectively feed back, and reaches energy-efficient purpose.
Novel permanent magnetic direct current machine provided by the utility model has simple in structure, energy-efficient advantage.Be used for that powered vehicle is energy-conservation to be reached more than 30%.
Description of drawings:
Fig. 1 is the cross-sectional view of this novel permanent magnetic direct current machine.
Fig. 2 is the carbon brush rotating disk of this novel permanent magnetic direct current machine and the structural representation of commutator.
1-stator wherein; The 2-rotor; 3-carbon brush rotating disk; The 4-commutator; The 5-carbon brush; The 6-rotating shaft.
Embodiment:
Describe the embodiment of this novel permanent magnetic direct current machine in detail below in conjunction with accompanying drawing.As shown in Figure 1 and Figure 2, this DC motor excitation stator adopts towards the silicon steel plate stacking of grooved hole and forms, and scribbles insulating varnish between sheet, to reduce the eddy current that produces when armature rotates.Excitation winding is placed in the wire casing by high strength insulated copper wire coiled coil and insulation processing in addition between winding and iron core.Commutator 4 is contained in an end of stator 1 armature, is made up of the wedge copper sheet, and separates with insulating material such as micas between copper sheet, forms a cylinder.Armature winding is welded in the afterbody of commutator 4 respectively, and it is to realize by commutator and carbon brush that armature winding connects with external power source.Brush partly is made up of carbon brush, brush carrier, spring etc., and carbon brush rotating disk 3 is installed on the main shaft of rotor, and carbon brush 5 symmetries are fixed on the edge of this rotating disk.
This motor rotor is by high-performance rare-earth permanent magnet material (amount of magnetizing is 4000 Gausses), and designing requirement becomes watt shape magnet, is contained in respectively on the aluminum alloy sleeve, forms N, the S utmost point by bolted.
