Abstract
A linear motor capable of effectively cooling heat generated when the linear motor is driven is provided where the motor includes a moving element having the lower portion with a plurality of field magnets. The motor includes a stator element having an upper portion with a my plurality or coil units arranged at a constant spacing, and heat dissipating members coupled to the stator element at constant spacing, for externally dissipating heat generated by the stator. An improved cooling effect can be achieved by the provision of heat pipes having heat dissipating fins formed thereon, or by use of thermoelectric semiconductor cooling modules.
