The brake motor magnetic force generator is characterized in that the magnetic force generator comprises an outer iron core and an inner iron core; the outer iron core is provided with an embedding groove; aluminium cores are cast between the outer iron core and the inner iron core and in the embedding groove to form a magnetic field loop; and the inner iron core is internally provided with a shaft hole which is matched with the rotary shaft. The magnetic force generator of the scheme adopts matching of a mechanical structure and the stator to form a magnetic field, can directly adopt three-phase alternating-current power, does not need a rectifier to convert the alternating-current power into direct-current power, and has the advantages of simple structure, easy manufacture, low cost and long service life.
Description
Technical field
The utility model relates to electric block, particularly relates to a kind of magnetic force generator of electric block braking motor.
Background technology
The braking motor of existing electric block mostly is Cone-shaped electric machine greatly, be that the motor afterbody is big, head is little, therefore stator and the rotor that is installed in the motor case also is taper, its shortcoming is that efficient is low, quick heating, the motor manufacturing technology complexity, therefore there is the people to design columniform electric block motor, and applied for China Patent No. 200520031409.6, name is called " a kind of cylindrical rotor brake motor electric block ", this scheme is installed electromagnet successively at the motor head, armature and taper brake disc, be provided with spring between armature and the electromagnet, electromagnet energising back forms magnetic field, pulling armature, armature is thrown off the taper brake disc, the work of motor energy normal rotation, after the electromagnet outage, armature is pushed outwards under the spring force effect, compresses with the taper brake disc, and motor shaft braking rapidly stops the rotation, but, the shortcoming that this scheme exists be electromagnet adopt be permanent magnet, be three-phase alternating current and motor adopts, but permanent magnet adopts direct current, so need by rectification circuit (rectifier), convert alternating current to direct current, complex structure makes trouble, damage easily, useful life is short.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of simple in structure, easy to manufacture, and cost is low, the electric block braking motor magnetic force generator of long service life.
The technical scheme of the utility model electric block braking motor magnetic force generator is: comprise casing, one end of casing is installed the brake end cap, stator is installed in the casing, rotor is installed in the stator, rotor is by the machine shaft driven rotary, be positioned at installation magnetic force generator on the rotor of stator, brake disc is slidingly connected in the rotating shaft, be equipped with brake spring between brake disc and the magnetic force generator, brake disc contacts with the brake end cap, it is characterized in that described magnetic force generator comprises outer iron core and interior iron core, be shaped on caulking groove on the outer iron core, reach cast aluminum core formation field circuit in the caulking groove between outer iron core and the interior iron core, be shaped on axis hole in the interior iron core, axis hole matches with rotating shaft.
Electric block braking motor magnetic force generator of the present utility model, described magnetic force generator comprises outer iron core and interior iron core, is shaped on caulking groove on the outer iron core, reaches cast aluminum core in the caulking groove between outer iron core and the interior iron core, the aluminium core is cast in the caulking groove, be the equal of that outer iron core and aluminium core intersect to form iron bar at interval, be embedded in the outer wall of aluminium core, during work, by the rotating shaft driven rotary, form axial magnetic field with stator, brake disc is inhaled down the motor operate as normal.The magnetic force generator of this programme adopts mechanical structure to cooperate with stator and forms magnetic field, can directly adopt three-phase alternating current, need not rectifier and converts alternating current to direct current earlier, and simple in structure, easy to manufacture, cost is low, long service life.
Electric block braking motor magnetic force generator of the present utility model is shaped on step on the described outer iron core, is shaped on groove on the step, and groove matches with the aluminium core, cooperates reliable.Be shaped on keyway on the described shaft hole inner wall, keyway matches with rotating shaft, and it is firm to connect.
