Embodiment

[0039] A tubular linear motor mover, such as Figure 1 to Figure 4 shown,

[0040] Including permanent magnet 21, iron core 22 and mandrel;

[0041] The iron cores 22 and the permanent magnets 21 are arranged alternately, so that the permanent magnets 21 are arranged between the iron cores 22 , the magnetic poles of the two adjacent permanent magnets 21 are opposite to each other, and the mandrels are arranged at the two ends of the magnets. The iron core 22 is away from the side of the permanent magnet, and the core shaft is slidably connected with the sliding sleeve 6 provided on the stator.

[0042] The tubular linear motor mover provided by the embodiment of the present invention can not only provide a magnetic field for the linear motor, but also can directly support the mover 2 on the sliding sleeve 6 of the stator through the mandrel to perform reciprocating linear motion without going through an intermediate conversion mechanism To directly generate linear motion, th...

Abstract

The embodiments of the present application belong to the technical field of electric motors, and relate to a tubular linear motor mover. The technical solution provided by this application includes permanent magnets, iron cores and mandrels; the iron cores and the permanent magnets are arranged in a staggered manner, so that the permanent magnets are arranged between the iron cores, and the magnetic poles of the two adjacent permanent magnets are opposite to each other. , the mandrel is arranged on the side of the iron core at both ends away from the permanent magnet, and the mandrel is slidably connected with the sliding sleeve arranged on the stator. The sliding structure between them does not need to occupy additional space, and the volume of the linear motor can be reduced, so that the linear motor can be applied to the occasions with stricter requirements on the volume of the motor. Therefore, the space occupied by the internal structure of the linear motor is better reduced, the internal structure of the motor is greatly optimized, the cost of the motor is reduced, and the manufacture and maintenance are easier.

Description

technical field [0001] The present application relates to the technical field of electric motors, and more specifically, to a tubular linear motor mover. Background technique [0002] A linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. It can be regarded as a rotating electrical machine which is cut radially and developed into a plane. The side derived from the stator is called the primary, and the side derived from the rotor is called the secondary. In practice, the primary and secondary are manufactured to different lengths to ensure that the coupling between the primary and secondary remains unchanged over the required travel range. Linear motors can be either short primary and long secondary, or long primary and short secondary. Considering the manufacturing cost and operating cost, take a linear induction motor as an example: when the primary winding is co...
