PURPOSE: A linear motor is provided to improve assembly efficiency by reducing the weight of a secondary member. CONSTITUTION: Two permanent magnet modules arrange a single combining module. A secondary member which uses four permanent magnets includes the two combining modules. The secondary member is assembled by inserting the two combining modules. A first permanent magnet module(20A) and a third permanent magnet module(20C) arrange a single first combining module(30A). A second permanent magnet module(20B) and a fourth permanent magnet module(20D) arrange a second combining module(30B). The first combining module comprises a permanent magnet in which the poles of the magnet are respectively arranged on upper and lower sides based on a position corresponding to a movement direction. The second combining module is comprised of one or more permanent magnet cases separated in the movement direction. Each permanent magnet case is inserted into a penetration hole of the first combining module. |
