Abstract

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.

Description

Technical field [0001] The invention relates to a cooling structure of an ultra-precision linear motor, belonging to the technical field of linear motors. Background technique [0002] The ultra-precision linear motor is an actuator that guarantees the operation of the ultra-precision servo system. With the development of nanotechnology and biotechnology, the requirements for thrust density and thrust accuracy of ultra-precision linear motors have gradually increased, which has brought about an increase in the current density of the motor windings and an increase in copper consumption. Since the current ultra-precision position servo system uses a laser displacement sensor, it has higher requirements for the constant temperature of the ambient temperature. However, due to the high integration density of the ultra-precision servo system, it is difficult to use ultra-precision linear motors during operation. To avoid dissipating heat to the outside world, the ultra-precision posit...
