Embodiment Construction

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] See figure 2 , the linear stepper motor of the present invention has a linear stator part A and a linear mover part B, which breaks the traditional mode of converting rotary motion into linear motion, and directly adopts a linear motion method. The linear stator part A is installed on the lower fixed slide On the upper surface of the...

Abstract

The present invention provides a linear stepping motor having a linear stator portion and a linear mover portion. The linear stator portion is fixed and stationary. The linear mover portion is positioned above the linear stator portion and carries a load to do linear motion. The linear stator portion comprises a permanent magnet. Both the upper and the lower surfaces of the permanent magnet are provided with first magnetizers. A plurality of tooth parts which deviate from the permanent magnet and are uniformly distributed extend out of the surfaces of the first magnetizers. The tooth parts oftwo first magnetizers are a staggered distribution, and the two first magnetizers have magnetism of different directions under the effect of the permanent magnet. The linear mover portion comprises amagnetic conductor formed by lamination, an energized coil winds around each pole of the magnetic conductor, and the tooth ends of teeth distributed in each pole is magnetic after the magnet is energized. A traditional mode of converting rotary motion to linear motion is broken, the mode of straight-line motion is directly adopted, the power output mode of the motor is improved, the output efficiency of the motor is improved, and the space is more saved.

Description

technical field [0001] The invention relates to the technical field of stepping motors, in particular to a linear stepping motor. Background technique [0002] As an actuator, the stepper motor is one of the key products of mechatronics. It is widely used in various automation control systems, involving many professional knowledge such as machinery, motors, electronics and computers. However, the current traditional stepping motors are all rotary motions, and the rotary motion is converted into linear motion through the transmission of gears or pulleys. The conversion efficiency is low, the structure is relatively complicated, and it is not easy to use. [0003] See figure 1 , The motor shaft 1 is threaded with a slider 2, the motor shaft 1 rotates, and the slider 2 converts the rotation into a linear motion under the action of the screw connection, and the load carried by the slider 2 completes the linear motion in the left and right directions , and then realize the torq...
