Abstract
The present invention relates to a linear motor with an improved cooling structure for cooling heat generated from a coil block of the motor. The linear motor includes a stator element having a stator element frame, a movable element having a movable element frame, adapted to linearly move along the stator, and a heat dissipation plate mounted on the stator element frame and the movable element frame, for externally dissipating heat generated from a coil block. Such a structure can prevent over-heating of the linear motor by dissipating heat generated from the motor coil to thereby cool the motor.
