Claims

[Scope of utility model registration request]

A running element comprising at least one drive magnet and a primary yoke that supports the drive magnet and forms a magnetic path, a plurality of flat coils arranged along the running direction of the running element, and the plurality of flat coils. It consists of a secondary yoke that supports a coil and forms a magnetic path, and includes a stator that slidably supports the running element, and a drive magnet position detection means for switching the direction of energization to the flat coil. In the linear DC motor, the drive magnet position detection means includes a position detection magnet disposed on the primary yoke separately from the drive magnet, and a position detection magnet disposed on the secondary yoke corresponding to the traveling trajectory of the position detection magnet. and a magnetic sensor arranged at a position to detect the magnetism of the position detection magnet.
