Abstract

A pipe type linear motor for electrical discharge machine generally comprises a stator, a rotor, a coil and a spindle. Wherein the rotor is mounted onto the hollow spindle, and then the rotor together with the hollow spindle are slidably disposed at the axial center of the stator, in the stator the coil is defined. After the coil is electrified, the rotor will be driven to reciprocate along the spindle by the electromagnetic force produced by the coil (on the spindle provided with predisposed device, such as electrical discharging head). By such an arrangement, the rotor can be driven by stable electromagnetic force, and the structure of the present invention is smaller than that of prior arts, furthermore, the spindle can be interiorly provided with wires as desired for reducing the control complexity of the linear motor, and thus both the production cost and installation space of the linear motor of the present invention can be substantially reduced.
