Abstract: A tubular linear motor for electrical discharge machine generally comprises: a stator, a forcer, a set of coils and a hollow central shaft. The forcer is mounted onto the hollow central shaft, the forcer and the hollow central shaft are slidably disposed at the axial center of the stator, the set of coils is disposed in the stator (or in the forcer). After the coil is powered, the forcer will be driven to reciprocate along the central shaft by the electromagnetic force produced by the set of coils. The central shaft can be interiorly provided with wires, and thus, both the production cost and installation space of the linear motor of the present invention can be substantially reduced.
