Abstract

The invention belongs to the technical field of motors and particularly relates to a winding type asynchronous motor and a manufacturing method. The problems of expansion stress difference between aniron core and a rotating shaft, magnetic short circuit and autorotation of a rotor after a power failure in an existing asynchronous motor are solved. The provided motor comprises a housing; a base isintegrally formed on the lower side wall of the housing; two hanging rings are welded to the upper side wall of the housing; a rotating shaft is arranged in the housing in a penetrating mode; a rotoris fixed to the outer wall of the rotating shaft; a stator arranged on the outer wall of the rotor in a winding mode is fixed in the housing; a mounting opening is formed in the connecting position of the housing and the rotating shaft; and a bearing is fixed in the mounting opening. By arranging the annular iron core, the motor is prevented from contacting the rotating shaft and expansion stressis reduced; by arranging mounting grooves and partition blocks, magnetic contact is avoided, and the electromagnetic performance is guaranteed; and by setting a magnetic plate and a reset spring, therotor is fixed during the power failure, and the safety performance is greatly improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a winding type asynchronous motor and a manufacturing method. Background technique [0002] Wound motors are a type of asynchronous motors. Asynchronous motors are divided into wound type and squirrel cage type according to the rotor winding form. [0003] The working principle of the asynchronous motor is that when the three-phase stator windings (with a phase difference of 120 degrees) of the motor are connected to the three-phase symmetrical alternating current, a rotating magnetic field will be generated, and the rotating magnetic field will cut the rotor winding, thereby generating induction in the rotor winding Current (the rotor winding is a closed path), the current-carrying rotor conductor will generate electromagnetic force under the action of the stator's rotating magnetic field, thereby forming an electromagnetic torque on the motor shaft, driving the motor to rotate,...
