Embodiment 1

[0029] Example 1, please refer to Figure 1-Figure 6 As shown, this embodiment provides a linear motor, including: a stator magnetic plate 1, a mover 2 and a power supply slide rail, the mover 2 is arranged above the stator magnetic plate 1, and there is a gap between the mover 2 and the stator magnetic plate 1 , the power supply slide rail is parallel to the moving direction of the mover 2, the mover 2 is provided with a conductive component 7, and the conductive component 7 abuts against the power supply slide rail.

[0030] In the linear motor provided in this embodiment, the mover 2 is located above the stator magnetic plate 1 and has a certain distance from the stator magnetic plate 1 . During operation, the mover 2 can move along the length direction of the stator magnetic plate 1 . The power supply slide rail is parallel to the moving direction of the mover 2, and is connected to an external power source, that is, the power line is connected to the power supply slide r...

Abstract

The invention provides a linear motor, which relates to the technical field of the motor. The linear motor comprises a stator magnetic plate, a mover and a power supply sliding rail, wherein the moveris arranged above the stator magnetic plate, a gap is arranged between the mover and the stator magnetic plate, the power supply sliding rail is parallel to the moving direction of the mover, and a conductive component is arranged on the mover, and the conductive component is in contact with the power supply sliding rail. The linear motor provided by the invention, when in operation, the power supply sliding rail is kept stationary, only the conductive component on the mover moves together with the mover, and does not need to be bent in the movement process, and only needs to be kept in contact with the power supply guide rail. The power cord does not need to be moved all the way to avoid fatigue damage caused by multiple bending. It also avoids that the aging of the chain affects the normal motion of the mover during the movement. The power guide takes up less space than the towed chain.

Description

technical field [0001] The invention relates to the field of motors, in particular to a linear motor. Background technique [0002] The traditional linear motion adopts the structure of "rotary motor + ball screw", and uses the screw structure to convert the motion in the direction of rotation of the rotary motor into the linear motion required by the application, but there are many problems in this transmission method. With the advancement of related technologies, the re-emerged linear servo motor (hereinafter referred to as "linear motor") in recent years has effectively solved the problem of the "rotary motor + ball screw" structure: the linear motor has no screw, so the length is not affected. The limitation of the length of the lead screw, the absolute accuracy, repeatability, maximum speed and maximum acceleration of the linear motor are higher. When working, the mover needs to be powered externally to enable the linear motor to run. Existing linear motors all adopt ...
