Sliding compression type asynchronous motor

Abstract

The invention discloses a sliding compression type asynchronous motor. The motor comprises an outer shell, a front end cover, a rear end cover, a rotating shaft, a stator, an insertion linkage mechanism, a rear end cover driving mechanism and a front end cover driving mechanism. A front end cover is slidably connected to the outer side of the periphery of the front end of an outer shell in a sleeving mode through a front end cover driving mechanism. The front-end driving screw is clamped and rotated on the front-end positioning block, so that the front-end threaded cylinder is driven to move axially, the front-end cover is driven to be tightly connected to the connecting ring body of the rotating shaft in a pressed mode, the axial position is moved flexibly and variably due to the convenience of sliding connection, and therefore the installation range is wider and more flexible.

technical field [0001] The invention relates to a sliding compression asynchronous motor. Background technique [0002] Asynchronous motor is a kind of induction motor, which is a type of motor powered by simultaneous access to 380V AC current. Since the rotor and stator rotating magnetic field of a three-phase asynchronous motor rotate in the same direction and at different speeds, there is a slip. Therefore, it is called a three-phase asynchronous motor; the speed of the rotor of the three-phase asynchronous motor is lower than that of the rotating magnetic field, and the rotor winding generates electromotive force and current due to the relative motion between the rotor winding and the magnetic field, and interacts with the magnetic field to generate electromagnetic torque to realize energy conversion. ; On the rotating shaft of the existing motor, in order to facilitate heat dissipation, cooling blades will be installed at the rear end of the rotating shaft.

[0002] Asynchronous motor is a kind of induction motor, which is a type of motor powered by simultaneous access to 380V AC current. Since the rotor and stator rotating magnetic field of a three-phase asynchronous motor rotate in the same direction and at different speeds, there is a slip. Therefore, it is called a three-phase asynchronous motor; the speed of the rotor of the three-phase asynchronous motor is lower than that of the rotating magnetic field, and the rotor winding generates electromotive force and current due to the relative motion between the rotor winding and the magnetic field, and interacts with the magnetic field to generate electromagnetic torque to realize energy conversion. ; On the rotating shaft of the existing motor, in order to facilitate heat dissipation, cooling blades will be installed at the rear end of the rotating shaft. When the shaft load is small, the cooling blades are not needed to blow and dissipate heat under the condition of good heat generation. In this case, the rotating shaft keeps driving the cooling blades to rotate, which is actually an additional load and increases the load on the motor. , so it is necessary to develop a motor that can open and close the heat dissipation blades according to actual needs; in addition, the existing front and rear end covers are generally fixed with the connecting ring rotating on the rotating shaft, so it is necessary to pre-precisely calculate the front and rear end covers and the connecting ring The position of the body increases the difficulty of mold processing, and the use is not flexible and changeable
