LINEAR MOTOR

摘要

PURPOSE: A linear motor is provided to improve the feature of the linear motor by effectively cooling a rotor and a stator of the linear motor when the linear motor is driven. CONSTITUTION: A linear motor comprises a stator and a rotor(56). A coil unit(53) is installed at the stator. A magnet is installed at the rotor(56). A thrust force is generated between the coil unit(53) of the stator and the magnet of the rotor(56). A cooling channel(3) having an inlet portion(1) and an outlet portion(2) in opposite to the inlet portion(1) is provided in such a manner that the cooling channel(3) passes through a back iron(50) of the stator. A blower is connected to a side of the cooling channel(3) so as to forcibly blow the pressurized air toward the cooling channel(3).
