LINEAR ELECTRIC MOTOR CAPABLE OF DISSIPATING HEAT ON BASIS OF VAPOR CHAMBER, AND HEAT DISSIPATION METHOD FOR LINEAR ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2024/032039
Kind Code:
A1
Abstract:
The present invention relates to a linear electric motor capable of dissipating heat on the basis of a vapor chamber, and a heat dissipation method for a linear electric motor. The linear electric motor comprises a base, wherein two rotor windings are fixed on the base side by side, a vapor chamber is embedded between the two rotor windings, the width of the vapor chamber is the same as that of the rotor windings, and a lower end of the vapor chamber abuts against an upper end of the base. Ohmic heat, which is generated by the two rotor windings, is rapidly transmitted to the base below by means of the ultrahigh thermal conductivity of the vapor chamber for heat dissipation, thereby realizing the efficient heat dissipation of the rotor windings. A heat dissipation path has an extremely small thermal resistance and high heat dissipation efficiency, such that heat is not easily accumulated even through the electric motor operates for a long time; therefore, the strength, hardness and other mechanical properties of a metal part can be maintained, the insulation duration and the service life of the electric motor are prolonged, and the safety is improved. In addition, little heat is transmitted to a workbench, such that the workbench is not prone to heat deformation to affect the positioning precision of a system.
