But in essence, two single-degree-of-freedom motors are installed together, which makes the overall volume of the equipment larger, which is not conducive to the installation layout
In order to achieve a compact layout, Chinese patent 201510282204.3 provides a linear rotary permanent magnet actuator with an interlaced pole structure. The entire mechanism has only a single stator and a single rotor, but it realizes linear motion and rotary motion. The electronic control requirements of magnetic actuators are complicated, which brings difficulties to the use of high-response and high-precision occasions

The invention discloses a moving coil type permanent magnet linear rotating motor stator which includes a sleeve-shaped outer stator core yoke. A first permanent magnet capable of generating a magnetic field for linear motion is positioned in a port of the outer stator core yoke. A second permanent magnet capable of generating a magnetic field for rotational motion is positioned in the other portof the outer stator core yoke. A third permanent magnet capable of generating a magnetic field for linear motion and rotational motion is positioned in the inner cavity of the outer stator core yoke.The moving coil type permanent magnet linear rotating motor stator can well realize two-degree-of-freedom movement of a rotor, and well realizes high thrust / large torque and high-precision control operation of a motor.
Description
Technical field [0001] The invention relates to the technical field of permanent magnet linear rotating motors, and specifically provides a moving coil type permanent magnet linear rotating motor stator. Background technique [0002] Traditional motors generally can only provide single-degree-of-freedom motion such as linear motion or rotary motion, but cannot realize the combined two-degree-of-freedom motion of linear motion and rotary motion. However, in systems such as semiconductor processing equipment and automated assembly, it is often necessary to realize a two-degree-of-freedom motion that combines linear motion and rotational motion. In order to realize the above-mentioned two-degree-of-freedom motion, usually the single-degree-of-freedom motion is converted into two-degree-of-freedom motion through an external transmission mechanism, but this operation will bring some problems, such as: ①It will make the accuracy of the actuator Due to more processing restrictions, the...
