Stack-type motor core manufacturing method, stack-type motor core, and motor

Abstract

The invention relates to a stack-type motor core manufacturing method, a stack-type motor core, and a motor. The method comprises the steps: A, enabling at least two motor core piece to be stacked and laminated; B, arranging one or more holes on the stack-type motor core, formed through stacking and laminating, in an axial direction; C, injecting adhesive into the holes through employing the dispensing technology; D, placing the stack-type motor core after the injection of the adhesive so as to solidify the adhesive. The stack-type motor core is easy to manufacture, is low in cost, is high in practicability, is wide in application range, can remarkably improve the binding force among all pieces in the stack-type motor core, can enable the stack-type motor core not to deform after winding, and enables the performance of the motor to be more stable and reliable.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a method for manufacturing a laminated motor body, a laminated motor body and a motor made by the manufacturing method. Background technique [0002] At present, various types of electromechanical equipment have been widely used, many of which are equipped with power devices such as motors. Usually, these existing motors include components such as housings, stators, and rotors, and generally use stamping processes to integrally form a monolithic motor body, and then stack these motor body monoliths to form a It is used to support the supporting body of the excitation winding, so that the rotor and the stator can form a relative rotational motion by cutting the magnetic force line during use. [0003] However, these existing motor products still have some deficiencies to be improved. For example, when multiple motor body pieces are stacked and pressed, the bonding force between t...

Problems solved by technology

[0003] However, these existing motor products still have some deficiencies to be improved.

For example, when multiple motor body pieces are stacked and pressed, the bonding force between these motor body pieces depends on factors such as the compression process used, the number of motor body pieces, etc., in some Under certain circumstances, it may not be possible to ensure sufficient bonding force between the single pieces of the motor body, which will affect the performance and safe use of the motor

In addition, for some motor bodies such as skewed stators, when the field winding is wound on it, since the field winding will exert tension in the circumferential direction, it may cause poles in these motor bodies. The body inclination angle deviates more or less from its expected value, which will cause the performance index of the motor to deteriorate or deteriorate, resulting in a decrease in the reliability of the motor
