  • Patent number: 9968002
    Abstract: The present invention provides a heat-transfer mechanism of a motor primary, wherein a heat-transfer member having a metallic body is sandwiched between a motor moving member and a bearing member, such that the heat-transfer member separates the bearing member from the motor moving member to prevent direct contact there-between while the heat-transfer member is used as a heat-conducting medium, and therefore, heat energy on the bearing member and the motor moving member can be gathered in the heat-transfer member, and the effect of effectively dissipating, by means of conduction, the heat energy from the motor moving member and from the bearing member driven by the motor can be achieved.

  • Patent number: 9774237
    Abstract: A slide-block-type shaft linear motor platform includes a mover and a stator. An air gap is defined between the mover and the stator. The air gap can communicate with outer side via a fluid inlet space. Accordingly, air convection can take place between the heat source, that is, the winding inside the mover and the outer side. Therefore, the heat generated by the winding can be continuously dissipated to prevent the components from deforming due to the heat. In this case, the precision of operation can be ensured and the performance of the motor will not deteriorate due to the heat.

  • Patent number: 9680354
    Abstract: A winding cooling structure of shaft motor includes a chamber in which multiple annular windings are received. A cooling fluid is filled up in the chamber to possibly contact the surfaces of every part of the respective windings. Therefore, heat generated by the windings can be quickly transferred to the cooling fluid around the windings and dissipated. Accordingly, in operation, the heat dissipation efficiency of the shaft motor can be enhanced to prolong lifetime of the motor and ensure the performance of the motor.
