Abstract

The invention discloses an implementation method of a linear motor for an automatic sliding door and belongs to the technical field of linear motors. The whole motor is provided with two sets of stators, wherein a circuit mainboard is arranged between the two groups of stators, an analog Hall device for detecting motor magnetic steel is arranged on the circuit main board, the stator and the circuit board are wrapped by an outer sheath and an upper cover, a rotor of the motor comprises a long aluminum strip, a row of magnetic steels are uniformly arranged at the bottom in a staggered manner, and the motor stator is plugged into the middle of a notch of a profile rail. Two machine meter screws on left and right end parts of the stator are screwed, the rotor is plugged into a sliding groove of a sectional material, stop block assemblies are locked at two ends of the sectional material, and after electrification, the motor stator can generate a three-phase alternating moving magnetic field, so the rotor does linear motion between the two stop blocks in the sliding groove, and the implementation method of the linear motor for the automatic sliding door is reasonable in structure.

Description

technical field [0001] The invention belongs to the technical field of linear motors, and in particular relates to a method for realizing an automatic sliding door linear motor with excellent performance. Background technique [0002] The early linear motor distance detection for automatic sliding doors used Schmidt-type switching Hall devices, and the detected motor movement distances were discrete jumps. For a conventional 12mm-width magnet, three uniformly distributed Hall The resolution of the device is 4mm. In order to further improve the motion control precision, the present invention uses an analog Hall device to obtain the current one-dimensional coordinate point where the mover is located by simulating the continuous change of the strength of the magnet detected by the Hall device. [0003] The early linear motors for automatic sliding doors were all driven by PWM. The disadvantages are that the torque fluctuates greatly and the electromagnetic noise is large. Moto...
