Problems solved by technology
However, in some cases, such as the limited length of the moving track and the need for a large stroke, this solution still cannot achieve the desired effect
[0003] Therefore, a new technology is needed to solve the problem of insufficient stroke of the magnetic suspension automatic door in the prior art when the length of the moving rail is limited

The invention discloses a linear motor, a magnetic suspension door actuation system and a magnetic suspension automatic door, and belongs to the technical field of magnetic suspension doors. The linear motor comprises a machine shell, a position sensor and at least two coil windings, wherein the machine shell is in a strip shape; the coil windings are sequentially arranged in the machine shell in a row, are sequentially connected in series and are used for generating magnetic force to push a movable rail; a magnetic member is fixed onto the movable rail; the position sensor is used for detecting the position of the movable rail; and the position sensor is located in a queue of the coil windings and is located between the two coil windings. According to the invention, the position sensor in the linear motor is moved from the end part of the coil windings of the motor to the queue of the coil windings, so that the stroke of the corresponding movable rail when the linear motor is used is increased, and the stroke can be increased without changing the length of the motor and the length of the movable rail.
Description
technical field [0001] The invention belongs to the technical field of magnetic suspension doors, and in particular relates to a linear motor, a magnetic suspension door operator and a magnetic suspension automatic door. Background technique [0002] As the application of maglev automatic doors becomes more and more widespread, some application scenarios with large strokes such as curtains, folding doors, and mobile galleries are gradually adopting maglev door operators. In the existing linear motors, the Hall sensor used to sense the position of the moving rail is set at one end of the motor. The stroke of the moving rail of the linear motor with this structure is relatively short, although multiple motors can be arranged in a row to drive A moving track increases the stroke, thereby increasing the range of movement of the door leaf. However, in some cases, such as when the length of the moving track is limited and a large stroke is required, this solution still cannot ach...
