Abstract
The utility model relates to a single-phase asynchronous motor capable of automatic brake in a magnetic circuit type. The utility model comprises a rotor (1), a stator winding (6), magnetic circuit sheets (7), a brake disc (5), and armature (9), wherein, the magnetic circuit sheets (7) are arranged in the stator winding (6), and the brake disc (5) is connected with the rotor (1); the armature (9) which can slide in an axial direction is arranged on the inner side of the brake disc (5); a spring (10) is arranged on the inner side of the armature (9), and the outer side of the armature (9) is provided with a friction sheet. The utility model is characterized in that the number of the magnetic circuit sheets (7) is four, and the magnetic circuit sheets (7) are respectively arranged in a slot on the stator winding (6). Because the four magnetic circuit sheets are adopted, the generated magnetic attraction force is one time stronger than that of the prior art, and the armature can be made quickly move left for accelerating the start of the motor.
Description
The utility model relates to a kind of motor.
In the prior art, the magnetic circuit type self-retention exchanges monopole asynchronous motor, comprise rotor, stator winding, be arranged at the magnetic circuit sheet in the described stator winding, the brake disc that is connected with described rotor, the armature in axial sliding of inboard that is arranged at described brake disc, the inboard of described armature is provided with and makes described armature shaft to the spring away from described magnetic circuit sheet, the outside of described armature is provided with friction plate, remain static down at described motor, described friction plate contacts with the inner surface of described brake disc.Described magnetic circuit sheet adopts two to differ 180 degree and arrange, and the magnetic adhesion that is produced when electrical power is apart from little, and makes and described armature discontinuity influence the rapid startup or the stall of motor.
The utility model purpose provide a kind of when electric motor starting or when having a power failure armature movement magnetic circuit type self-retention rapidly exchange monopole asynchronous motor.
For achieving the above object, the technical solution adopted in the utility model is: a kind of magnetic circuit type self-retention exchanges monopole asynchronous motor, comprise rotor, stator winding, be arranged at the magnetic circuit sheet in the described stator winding, the brake disc that is connected with described rotor, be arranged at the armature in axial sliding of the inboard of described brake disc, the inboard of described armature is provided with and makes described armature shaft to the spring away from described magnetic circuit sheet, the outside of described armature is provided with friction plate, remain static down at described motor, described friction plate contacts with the inner surface of described brake disc; Described magnetic circuit sheet has four, is installed on respectively in the groove on the described stator winding, and the distance between the described adjacent magnetic circuit sheet equates and differs 90 degree.After the motor energising, except that most of magnetic flux through the rotor core induced current, produce the torque, other has the fraction magnetic flux through the magnetic circuit iron core, radial flux is changed into axial magnetic flux, form the loop by armature in axial sliding, at this moment axial magnetic flux produces axial suction between magnetic circuit iron core and armature, armature shaft is moved to left-hand, the compression spring also drives the brake strip that is installed on the armature, makes it to break away from the brake disc on the armature spindle, and rotor and brake disc begin rotation.After the outage, axial magnetic suction disappears, and armature and friction plate are resetted, and makes friction plate contact with brake disc and produces friction brake force, makes the rapid stall of motor.
Because the utilization of such scheme, the utility model compared with prior art has following advantage:
Owing to adopted four magnetic circuit sheets, therefore the magnetic attraction that is produced is twice than prior art, can make that armature moves to left rapidly, add the startup of speed motor, but the suction stepless action of described magnetic circuit sheet makes armature movement reliable and stable on armature.
