The invention provides a compact firm motor, which comprises a front end cover, a back end cover as well as rotational components installed within the end covers, wherein surrounding edges extending outwards are arranged respectively on openings of the front and back end covers, through holes are formed in the surrounding edge of the back end cover, cylindrical platforms are arranged on the surrounding edge of the front end cover, the cylindrical platforms and the through holes are corresponding in position and spaced uniformly, screw holes are cut through in the cylindrical platforms, the front and back end covers are fixed by self tapping screws, and heat dissipation holes are formed in the outer wall of the front end cover. According to the motor, the design is reasonable, the fixing ability is strong, nuts and washers in the conventional motor are not needed, and the use is convenient and effective.
Description
Technical field
The present invention relates to a kind of motor, particularly a kind of compact firm type motor.
Background technology
The excitation mode of direct current machine refers to how excitation winding is powered, produced magnetic flux gesture and set up the problem of main field, according to the difference of excitation mode, direct current machine can be divided into following several types.After the excitation winding of series DC machine is connected with armature winding, then be connected to DC power supply, the exciting current of this direct current machine is exactly armature supply, and compound DC machine has shunt excitation and two excitation winding of series excitation.If the identical cumulative compound excitation that is called of magnetomotive force direction that the magnetomotive force that series excitation winding produces produces with shunt winding.If two magnetomotive force opposite directions, are called differential compound.
The direct current machine of different exciting mode has different characteristics, and the main excitation mode of ordinary circumstance DC motor is shunt excitation formula, series excitation formula and compound-wound, and the main excitation mode of DC generator is separated exciting, shunt excitation formula and and compound-wound.
Brushless DC motor is to adopt semiconductor switch device to realize electronic commutation, with electronic switching device, replace traditional contact commutator and brush, the advantage such as it has that reliability is high, non-commutation spark, machinery noise are low, is widely used in high-grade deck, video tape recorder, electronic instrument and automated office equipment.
Brushless DC motor is comprised of permanent magnet rotor, multipole winding stator, position transducer etc.Position sensing is pressed the variation of rotor-position, along a graded, the electric current of stator winding being carried out to the change of current (is the position of detection rotor magnetic pole relative stator winding, and produce position sensor signal in definite position, after processing, signaling conversion circuit removes power ratio control switching circuit, by certain logical relation, carry out winding current switching), the electronic switching circuit that the operating voltage of stator winding is controlled by position transducer output provides.
Position transducer has Mageneto-sensitive type, photoelectric type and electromagnetic type three types.Adopt the brushless DC motor of Mageneto-sensitive type position transducer, its magneto-dependent sensor part (explain archaic or dialectal words in current language such as Hall element, magnetodiode, magnetosensitive utmost point pipe, magnetoresister or application-specific integrated circuit (ASIC) etc.) is contained on stator module, the changes of magnetic field producing while being used for detecting permanent magnet, rotor, common motor component is more, when screw bolt and nut is tightened, due to overexertion, usually there is the phenomenon of fracture, to assembling, brought inconvenience.
Above-mentioned known, be necessary prior art further to improve.
Summary of the invention
Technical problem to be solved by this invention is not enough for prior art, proposes a kind of crystallized ability strong, has saved nut and bullet pad in conventional motors, effective motor easy to use.
The present invention is achieved by the following technical solutions:
The invention provides a kind of compact firm type motor, comprise front end housing, rear end cap, and be arranged on the runner assembly in end cap, described front end housing, rear end cap arrange respectively outward extending surrounding edge at opening part, on the surrounding edge of described rear end cap, offer through hole, surrounding edge at described front end housing is provided with cylinder table, described cylinder table is corresponding with lead to the hole site and interval is even, described cylinder table is provided with the screw of perforation, rear end cap is fixed by tapping screw and front end housing, on the outer wall of described front end housing, is provided with louvre.
