Title:
AXIAL WINDING-TYPE MOTOR
Document Type and Number:
WIPO Patent Application WO/2020/184811
Kind Code:
A1
Abstract:
The present invention relates to a motor and, more specifically, to a motor capable of effectively cooling heat generated by a coil without having a separate cooling member. The axial winding-type motor according to the present invention comprises: a rotor; and a stator. Here, the stator has a core and a coil. The coil has a rectangular bar-shaped and flat-angled cross section and is wound with one end in the width direction of the core, and then wound along the longitudinal direction of the core. According to the present invention, the coil wound around the core is formed of a hollow tube, and when a refrigerant flows inside the tube, heat generated by the coil can be directly absorbed and cooled. Therefore, it is possible to prevent damage caused by heat generation of the coil, thereby improving durability of the motor and preventing failure of peripheral parts. In addition, according to the present invention, the cross section of the coil wound around the core is rectangular bar-shaped and flat-angled and is wound with one end in the width direction of the core and wound along the longitudinal direction of the core. In this case, efficiency of the motor can be increased.
