For most linear motors, achieving high precision and miniaturization while ensuring certain performance requires providing good heat dissipation conditions.
The heat of the linear motor is mainly from ohmic heat generated when the rotor winding works. Based on the current liquid-cooled linear motor winding structure, the heat generated by the winding needs to be transferred from the winding far away from the liquid-cooled plate to the winding near the liquid-cooled plate, then transferred to the winding base or the iron core lamination through the insulating layer, and finally transferred to the liquid-cooled module to realize heat dissipation. However, the heat dissipation path has high thermal resistance and low heat dissipation efficiency, and the motor is easy to accumulate heat after long-term operation and even has a burn-in phenomenon. Meanwhile, when the temperature inside the motor is high, the insulation life of the motor is correspondingly reduced, and the strength, hardness and other mechanical properties of metal parts are also reduced, so that the service life and safety of the motor are seriously influenced.
