Abstract

A rotor of a wound rotor driving motor includes: a rotor body that is rotatably installed at a predetermined air gap at an inside of a stator and in which a rotor coil is wound in a plurality of rotor teeth; and an end coil cover that is mounted at each of both sides of an axial direction of the rotor body in order to prevent the rotor coil from separating, where the rotor body forms a plurality of air movement passages that are open to the outside in an axial direction, and the end coil cover forms a plurality of connection passages that are connected to the air movement passage.

Description

technical field [0001] The present invention relates to a wound rotor driving motor, and more particularly, to a rotor cooling structure of a wound rotor driving motor that can cool rotor coils with external air as an open structure by utilizing a non-molding method. Background technique [0002] In general, a hybrid vehicle or an electric vehicle can generate driving torque by an electric motor (hereinafter referred to as a "driving motor") that obtains torque from electric energy. [0003] For example, a hybrid vehicle is configured to be driven: in an electric vehicle (EV) mode, which is a pure electric vehicle using only the power of a driving motor; Electric vehicle (HEV) mode driving. Generally, electric vehicles are driven using the torque of a drive motor as a power source. [0004] A driving motor used as a power source in an environment-friendly vehicle mostly uses a permanent magnet synchronous motor (PMSM). For such PMSMs, it is necessary to maximize the perfo...
