Claims

[Scope of utility model registration request]

A U-shaped groove is provided in a flat iron core in which strip-shaped thin iron plates are laminated and heat exchanger plates of good thermal conductivity are sandwiched at predetermined intervals in the direction of lamination. In a flat linear motor in which a cooling pipe through which a cooling medium flows is fixed and a part of a coil is disposed outside the U-shaped groove, a heating motor is provided with a U-shaped groove for storing the coil at the end of the flat iron core. A heat transfer structure of good conductivity is provided, a coil placed outside the U-shaped groove is housed in the U-shaped groove, and the cooling pipe is fixed to the heat transfer structure. Cooling device for linear motor.
