Abstract

A drive motor is provided in which a coil is cooled in a three-dimensional manner. The drive motor includes a coil multi-cooling path through which oil collected by centrifugal force of a rotor flows to an engine clutch from an internal space of a rotor sleeve to be scattered in forward and backward directions of a coil and simultaneously flows to a resolver from an external space of the rotor sleeve to be scattered in the backward direction of the coil.
