  • 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.
