Abstract

The invention discloses a linear stepping motor used for dot matrix image forming and tactile feedback. The linear stepping motor comprises a rotor, a stator component and a shell, wherein the rotor is mounted in the shell through a guiding piece; the stator component sleeves the exterior of the rotor and is mounted in the shell; the shell comprises a sleeve-shaped outer shell and a contact pin seat; the rotor is of a stepped shaft structure in which a plurality of annular grooves are uniformly formed along the axial direction at intervals; the rotor is accurately mounted on the central axis of the shell through the guiding piece; the guiding piece comprises a first sliding bearing, a second sliding bearing, a gasket, a rubber sleeve and a rotor; the stator component sleeves the exterior of the rotor between the first sliding bearing and the second sliding bearing, and comprises a stator iron core, two coil windings and three permanent magnet rings; each coil winding is formed by serially and electrically connecting two non-skeleton self-adhesion coils in opposite directions mainly. The linear stepping motor is high in kinematics precision and small in volume, linear movement of the rotor is directly realized, and the motor can be used for 3D dot matrix image forming, tactile feedback and precision linear transmission.

Description

technical field [0001] The invention relates to a linear stepping motor, in particular to a linear stepping motor used for dot matrix image forming and tactile feedback, which can directly realize the linear motion of the mover. Background technique [0002] A linear motor is an electrical device that uses electric energy to directly generate linear motion. This kind of electrical equipment was proposed as early as 1845. However, in many occasions that require linear motion, almost all of them use technically mature rotating motors, and then pass through intermediate conversion devices such as chains, wire ropes, conveyor belts, racks or screw rods. And other mechanisms, because these equipment or systems have intermediate conversion transmission mechanisms, so the whole machine has problems such as large volume, low efficiency, and low precision. [0003] The linear stepping motor can convert the electric pulse signal into a linear displacement, that is, when an electric p...
