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.
Claims16
A drive motor, in which a coil is cooled in a three-dimensional manner, comprising:
- 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.
An eco-friendly vehicle, comprising:
- a coil multi-cooling path including:
- a coil cooling path and an engine clutch cooling path, which are formed at intervals in a rotor sleeve such that oil collected by centrifugal force of a rotor flows to an engine clutch from an internal space of the rotor sleeve to be scattered in forward and backward directions of a coil;
- and
- a resolver cooling path through which the oil flowing to a resolver from an external space of the rotor sleeve is transferred to the engine clutch cooling path to be scattered in the backward direction of the coil;
- and
- an auto transmission fluid (ATF) supplied as the oil.
