2results about "Propulsive transmission drive" patented technology

The propulsion unit including a casing having an inner curved surface and an outer curved surface, at least one tire disposed within the casing within a duct defined by the inner curved surface and the outer curved surface, a first propeller and a second propeller having a plurality of blades extending from within the casing toward a center axis of the casing, and one or more motors housed within the casing, the one or motor being configured to operate the at least one tire, the first propeller, and the second propeller independently of one another. There is also provided a vehicle with one or more propulsion units of the present disclosure.

The present invention relates to a pod drive that can improve the cooling performance of a built-in motor. An embodiment comprises a motor that is disposed inside a pod and provided with a stator and a rotor in order to provide rotational force to a drive shaft. The stator includes: a stator core that is fixed inside the pod and surrounds the drive shaft; a coil that is wound around the stator core; a plurality of stator channels through which a refrigerant flows and which are arranged along the axial direction of the stator core and extend in a circumferential direction inside the stator core; and a plurality of stator guides which extend radially and are arranged, spaced a certain distance from each other along the circumferential direction of the stator, in each of the stator channels. At least some of the plurality of stator guides may include a curved portion formed by curving radial outer ends.
