Embodiment Construction
[0019] The linear stepping motor is a product that uses the principle of magnetic levitation pole repulsion to directly drive the workpiece to perform complex space trajectory movement; and the position sensing system sends the signal of the detected movement to the control when the linear stepping motor moves. The device enables the movement of the linear stepping motor to have the function of position feedback.
[0020] 1 is a schematic diagram of a linear stepping motor position sensing system of the present invention, wherein the position sensing system includes a magnetic sensor 20 and a residual magnetic field stabilizing device 10, and the magnetic sensor 20 is completely surrounded by the residual magnetic field stabilizing device 10, when When the position sensing system moves in any direction on the stator 30 of the linear stepping motor, it uses the principle of magnetic induction to sense the change of magnetic flux between the stator 30 and the magnetic sensor 20, ...
