Abstract

The invention discloses an iron core and a linear motor, and belongs to the field of power equipment. The iron core is composed of an iron core material and a curing layer wrapping the surface of the iron core material, the iron core material is a soft magnetic material, and the curing layer is a polyurea material. The invention is applied to the aspect of a long stator iron core of a linear motor, solves the problems that the service life of a curing layer is short and the performance of the iron core is influenced in the existing iron core taking epoxy resin as the curing layer, and provides the iron core which has the characteristics of being capable of effectively reducing the thickness of an air gap between a mover iron core and a long stator iron core, reducing magnetic resistance, improving the efficiency of the motor, increasing magnetic conduction area, improving magnetic flux, reducing magnetic leakage, improving motor efficiency, and being long in service life, short in curing time and high in production efficiency.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to an amorphous long stator iron core and a linear motor which are applied to a linear motor and made of amorphous strips through lamination. Background technique [0002] Power electronic products develop very rapidly and are widely used in various fields of production and life. The application scenarios of different products are different. Among them, some products operate in outdoor environments. If the protection is not proper, the soft magnetic material inside the product will be easily corroded and aged, and the performance will decline. [0003] In order to overcome the above problems, iron core products such as motors and transformers are often cured with epoxy resin on the surface. On the one hand, the overall strength of the iron core is increased, and on the other hand, the iron core is completely sealed to prevent corrosion and aging of the iron core. Howev...
