The invention relates to a cooling structure for an ultraprecise
linear motor and belongs to the technical field of linear motors. The cooling structure solves the problem of proneness to heat exchange with environment caused by high side temperature of two-side surface-mounted cooling structures of existing linear motors. The cooling structure comprises a winding supporting portion, a winding and a heat conductive portion, wherein the winding is fixed on the surface of the winding supporting portion, the heat conductive portion is arranged on the surface on the outer side and fixedly connected with the winding supporting portion, the heat conductive portion is a
copper foil ring which fits the outer profile of the winding and is sleeved and fixed on the surface on the outer side of the winding, or the heat conductive portion is a
copper foil heat conductive ring formed by arraying multiple
copper foil sections in a dispersed manner, the
copper coil heat conductive ring fits the outer profile of the winding, and each
copper coil section is fixed on the surface on the outer side of the winding. The cooling structure for the ultraprecise
linear motor is suitable for cooling of linear motors.
