Embodiment Construction

[0015] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 with figure 2 As shown, the high-precision motor core of the present invention includes a rotor 1 and a stator, and the stator includes a main shaft 2, an aluminum core 5 and a punching sheet 6, the punching sheet 6 is embedded with coil windings, the main shaft 2 is fixed on the aluminum core, and the punching sheet 6 is located on the outside of the aluminum core. The basic structure of the rotor and the stator will not be repeated here. The main shaft is provided with a flange 9, the flange is perpendicular to the axis of the main shaft, a screw hole is arranged on the flange, and a screw hole matched with the flange is arranged on the aluminum core, and the flange is fixed on the aluminum core through the screw hole. on the core. The aluminum core and the die are kept fixed by a flat key.

Abstract

The invention discloses a high-precision motor core, which comprises a rotor and a stator, wherein the stator comprises a main shaft, an aluminum core and a punching sheet, the punching sheet is embedded with a coil winding, the main shaft is fixed on the aluminum core, the punching sheet is located at the outer side of the aluminum core, the main shaft is provided with a flange, the flange is perpendicular to the axis of the main shaft, the flange is provided with a screw hole, the aluminum core is provided with a screw hole matched with the flange, and the flange is fixed on the aluminum core through the screw hole. The flange base body and the fixing screw are fixed in a matched mode, high-precision matching in the machine core is guaranteed, and mechanical damage caused by resonance is reduced; the wiring structure can form an insulated wiring groove, and the wiring harness is arranged in the wiring groove to be separated from the aluminum core, so that the abnormal contact between the aluminum core and the wiring harness is avoided, the mutual influence is reduced, and the stability of the motor is improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a high-precision motor movement. Background technique [0002] When the magnetic field generated by the stator of the motor interacts with the magnetic field generated by the rotor, the rotor of the motor will run; after the stator of the motor is powered on, a magnetic field will be generated around it; the rotor will generate induced electromotive force in the magnetic field, and in the closed loop There is current passing through the rotor circuit, and a magnetic field is also formed around the rotor; when the two magnetic fields have the same polarity, repulsion will occur; in the process of constantly changing the phase sequence of the stator power supply of the motor, the magnetic field of the stator is also constantly changing. change, the motor keeps turning. [0003] The fixed part of the motor is called the stator (stator), on which a pair of stationary main poles of DC...
