Efficiently and effectively utilize the magnetic flux of the magnet at 360 degrees! It is a highly efficient and rigid linear motor.
Inside the shaft, there is a structure where magnets are joined with N poles facing each other and S poles facing each other, generating strong magnetic field lines from the junction. When current flows through the coil surrounding this shaft, a magnetic field is generated, and thrust is produced according to Fleming's left-hand rule. This thrust causes the coil (slider) to move if the shaft is fixed, and if the slider is fixed, the shaft operates. Additionally, unlike conventional linear motors, this design effectively utilizes the magnetic flux of the magnets without waste in a 360-degree manner, not only generating significant thrust with high efficiency but also maintaining a constant thrust regardless of any eccentricity in the shaft, resulting in a linear motor with high rigidity.

basic information
The shaft motor series includes the S series (standard), L series (designed for ease of use with a wider gap between the shaft and the movable part for longer lengths), and SX series (a type that improves thrust), all organized by shaft diameter. The coils are divided into two sets (D type), three sets (T type), and four sets (Q type) of UVW sets. We provide shaft motors that match the desired thrust based on the combination of shaft diameter and movable part.
