Problems solved by technology

[0003] Although the linear motor has many advantages compared with the traditional rotary motor, the efficiency and power factor of the linear motor are much lower than the rotary motor with the same capacity, especially at low speed, which is mainly due to two aspects Causes: First, due to the edge effect caused by the disconnection of both ends of the iron core of the linear motor stator (equivalent to the stator of the rotary motor), the edge effect will cause problems such as waveform distortion, and the result will directly increase the loss of the motor. Thereby reducing the efficiency and power factor of the linear motor, the second is that the PCB board of the linear motor is usually arranged on the mover (equivalent to the rotor of the rotary motor), and the armature coil with large heat generation is also arranged in the mover, which will cause Directly affect the heat dissipation of the linear motor, thereby reducing the efficiency and power factor of the linear motor

Embodiment 1

[0023] Such as figure 1 As shown, this embodiment provides a PCB linear motor, including a motor control system, and also includes a magnetically coupled stator 1 and a mover 2. The stator 1 includes a main stator 101 and two butt joints with the two ends of the main stator 1, respectively. The auxiliary stator 102, the mover 2 includes a main mover 201 and an auxiliary mover 202 docked with one end of the main mover 201, and the auxiliary mover 202 is provided with a PCB circuit board 3 connected to the motor control system.

[0024] What needs to be explained here is that the edge effect of the linear motor is not only reflected on the stator, but also on the mover. Setting the auxiliary mover on the mover can reduce the edge effect of the linear motor on the one hand, and on the other hand can also reduce the edge effect of the linear motor. The PCB circuit board is arranged in it, which can reduce the heating problem of the active element, which is not only beneficial to t...

The stator of the linear motor is designed to a structure of combination of the main stator and the auxiliary stators, the moverof the linear motor is designed to the combination of the main mover and the auxiliary mover, and the PCB is arranged in the auxiliary mover so as to improve the heat dissipation efficiency of the linear motor while reducing the end effect of the linear motor.

Description

technical field [0001] The invention relates to the field of motors, in particular to a PCB linear motor, an empty rail traveling mechanism and an empty rail train. Background technique [0002] In many fields, the motion path of the controlled object is often in the form of a straight line. For a long time, people have obtained the final linear motion, one-way displacement or two-way reciprocating movement through a rotating motor plus a mechanical transformation link. Obviously, this acquisition The way of linear motion has an "indirect" nature, which requires an intermediate mechanical transmission conversion device to convert circular motion into linear motion. In order to avoid the use of intermediate devices, linear motors are born for operation. Because linear motors have fast speed, simple structure and stable work , high sensitivity, low cost and other advantages, linear motors have been used in more and more fields, especially in transportation, mechanical loading ...
