Embodiment Construction

[0022] Further illustrate the embodiment shown in accompanying drawing below:

[0023] See attached picture. figure 1 Shown is a cylindrical linear motor composed of cast iron columns of the motor. The mover 5 is installed in the stator 4, wherein the pig iron is composed of pig iron columns, and the pig iron columns are assembled by unit integral sections with slits or slots 3 cast iron column. The whole pig iron column section is processed with ferromagnetic material, and there are winding cavity warning for installing winding and slot holes for lead wire and mechanical fixing. The pig iron column is fixed by the end cover 6, and the end cover 6 is also used as a part of the pig iron column to conduct magnetism. The pig iron column is in the shape of a cylinder as a whole. 2 is a ring-shaped winding, which is embedded in the pig iron column. On the pig iron column of the cylindrical pig iron, a slit or slot 3 for blocking the eddy current circle is provided along...

Abstract

The invention discloses a cast iron pillar for a motor. According to the invention, as for a cylindrical linear motor formed by the cast iron pillar, a rotor is installed in the stator, and the cast iron is formed by the cast iron pillar which is assembled by an integral unit segment with a kerf or groove; the overall cast iron pillar segment is made of ferromagnetic material, in which winding cavities for mounting windings and groove holes for lead wires and mechanical fixing are formed; the cast iron pillar is fixed by end covers which are part of the cast iron pillar and have a magnetic conducting function. Moreover, the cast iron pillar is cylindrical as a whole.

Description

technical field [0001] The invention relates to a motor, in particular to a magnetic circuit pig iron column part for the motor. Background technique [0002] Pig iron columns are important components of electromechanical equipment working in electromagnetic fields. In the alternating electromagnetic field, pig iron is always accompanied by iron loss, and its eddy current loss is equivalent to the presence of a short-circuited secondary coil. In some cases, the eddy current loss will even cause the effective magnetic flux to drop suddenly, resulting in a decrease in output. The eddy current loss of the cylindrical pig iron in the existing linear motor is actually very prominent. Contents of the invention [0003] The present invention aims to solve the above-mentioned problem of reducing the eddy current loss of the pig iron column of the motor. [0004] The working principle of the invention is based on effectively blocking the eddy current loop on the pig iron column...
