Linear motor structure based on PCB

Abstract

The invention discloses a linear motor structure based on a PCB. The linear motor structure comprises the PCB, an iron core, coils and insulating sleeves, the insulating sleeves are distributed in the iron core at intervals, and the coils are respectively arranged in the insulating sleeves; the PCB is arranged at one side of the iron core, the PCB is provided with connecting ports in one-to-one correspondence with the coils at intervals, and the coils are respectively provided with the wire outlet heads which extend to the outer sides of the insulating sleeves and are electrically connected with the corresponding connecting ports; the PCB is internally provided with the copper foil circuits which are connected with the connecting ports for connecting the coils in series or in parallel. Through the above mode, according to the linear motor structure based on the PCB, the PCB is specially designed to be connected with each coil, so that the series connection or parallel connection of the coils is achieved; the problems of line winding and electric leakage at the welding positions are avoided, therefore, an eddy current effect is avoided, the welding construction is more efficient, and the operation stability of the linear motor can be improved.

Description

technical field [0001] The invention relates to the field of linear motors, in particular to a structure of a linear motor based on a PCB board. Background technique [0002] The coils in the linear motor need to work in series or in parallel. In the production process of linear motors, the conventional method is to connect individual coils in series or in parallel by welding. The disadvantages of this method are: [0003] 1. Due to the large number of coils, it is easy to make mistakes when the wire ends are connected in parallel or in series; [0004] 2. The insulation of the welding place is difficult to deal with, and it is easy to cause leakage problems; [0005] 3. The welding workload is heavy, and false welding is prone to occur; [0006] 4. Multiple wires are entangled together, which will produce eddy current effect and affect the smooth operation of the linear motor; [0007] 5. It is not easy to operate and the production efficiency is low. [0008] The above...
