Abstract

Disclosed herein is a concentrated winding type coil connecting structure of a driving motor for a hybrid vehicle. A protrusion protrudes upwards (the axial direction of the motor) from each of U- / V- / W- / N-phase conducting plates concentrically inserted into receiving grooves of a conductor holder, and a bent part is bent from the upper end of the protrusion in a radial direction of the motor, and a curved groove is formed in an end of the bent part to surround the circumferential surface of each of the coils, so that a connector integrally having the protrusion, the bent part and the groove allows each conducting plate and the coil to be firmly joined to each other, thus maintaining a strong force of connection between the conducting plate and the coil, and providing high workability and durability.

Description

Technical field [0001] The present disclosure relates to a concentrated winding type coil for a drive motor of a hybrid vehicle. In a particularly preferred embodiment, the present invention relates to a concentrated winding type coil for a drive motor of a hybrid vehicle that maintains a firm connection between the conductive plate and the coil of the motor. Background technique [0002] The distributed winding type motor does not require a coil connection structure, but the concentrated winding type motor requires a coil connection structure. In a typical concentrated winding type motor, a toroidal coil is used as a conductor for connecting the coils, and the conductor is formed by bending. In addition, the conductor is axially laminated on the outside of the wire groove in a ring shape. In order to connect the conductors with the coils of the respective wire slots, their ends are melted and welded using additional connecting parts. [0003] figure 1 It is a schematic diagram ...
