Electric rotating machine with means for draining cooling fluid from a rotor compartment

A method for removing a fluid from a rotor compartment holding a rotor of an electric rotating machine having a stator, wherein the fluid originates from a fluid system for cooling one or more of the rotor and stator, wherein the electric rotating machine comprises:

• the stator;
• the rotor rotatable about an axis of rotation in relation to the stator;
• the rotor compartment;
• the fluid system for cooling the stator;
• and
• a fluid-guiding member having a front and a back,
• wherein the fluid-guiding member comprises a guide for guiding a fluid, and
• wherein the guide extends from the front of the fluid-guiding member toward the back of the fluid-guiding member,
• wherein the guide is immovable in relation to the stator, and
• wherein the method comprises:
• guiding a fluid from the front of the fluid-guiding member via a peripheral opening to the back of the fluid-guiding member by way of the guide and upon rotation of the rotor to remove a fluid from the rotor compartment.

A vehicle comprising one or more electric rotating machines, wherein said one or more electric machines comprises

• a stator;
• a rotor rotatable about an axis of rotation in relation to the stator;
• a rotor compartment holding the rotor;
• a fluid system for cooling the stator;
• and
• a fluid-guiding member having a front and a back,
• wherein the fluid-guiding member comprises a guide for guiding a fluid,
• wherein the guide extends from the front of the fluid-guiding member toward the back of the fluid-guiding member,
• wherein the guide is immovable in relation to the stator, and
• wherein the guide is configured to guide a fluid from the front of the fluid-guiding member via a peripheral opening to the back of the fluid-guiding member upon rotation of the rotor to remove a fluid from the rotor compartment.

An electric rotating machine comprising:

• a stator;
• a rotor rotatable about an axis of rotation in relation to the stator;
• a rotor compartment holding the rotor;
• a fluid system for cooling one or more of the rotor and stator;
• and
• a fluid-guiding member having a front and a back,
• wherein the front of the fluid-guiding member faces the rotor compartment while the back of the fluid-guiding member faces away from the rotor compartment,
• wherein the fluid-guiding member has a periphery surrounding the axis of rotation,
• wherein the fluid-guiding member comprises a guide for guiding a fluid, wherein the guide extends from the front of the fluid-guiding member toward the back of the fluid-guiding member, wherein the guide is configured to guide a fluid from the front of the fluid-guiding member to the back of the fluid-guiding member upon rotation of the rotor to remove a fluid from the rotor compartment,
• wherein the guide comprises two opposing sloping surfaces for guiding a fluid,
• wherein the guide adjoins the periphery of the fluid-guiding member at the front of the fluid-guiding member,
• wherein the guide comprises one or more ramps, and
• wherein at the front of the fluid-guiding member the periphery of the fluid-guiding member and each one of one or more of the one or more sloping surfaces are joined via the one or more ramps.
