Motor operating module

Abstract

Disclosed is a motor operating module, where the motor operating module includes a motor including a rotor and a stator, a gear unit provided on one side of the motor, and being configured to receive torque of the rotor and to transmit the torque to outside, and a housing configured to accommodate the motor and the gear unit in an inner space, wherein the inner space of the housing comprises a front space formed on a first side of the motor, a rear space formed on a second side of the motor opposite to the first side, rear-facing connection flow paths extending from the front space toward the rear space and providing a path for a cooling fluid to flow, and the cooling fluid is churned by the rotation of the gear unit to flow from a lower region of the housing into the rear space via the rear-facing connection flow paths. According to the present disclosure, a motor may be cooled by using a churning effect of an oil caused by rotation of a gear without a separate operating device such as a pump.

Dependencies are inferred from the claim text.
