Claims

[Scope of utility model registration request]

A linear motor is constructed by arranging permanent magnets with alternating polarities on the upper surface of the secondary base in the longitudinal direction, and providing an armature facing the permanent magnets on the lower surface of the primary frame. a rack provided on the primary side frame, a pinion rotatably provided on the primary side frame and meshing with the rack, and the rotation of this pinion is transmitted to drive the armature, which is opened by energization, and is de-energized and braked when an emergency stop is to be performed. A linear motor emergency stop device comprising: a rotary electromagnetic brake that operates; and a rotary encoder that is provided coaxially with the rotary electromagnetic brake and detects the position of the primary frame with respect to the secondary base. .
