Embodiment Construction

[0039] figure 1 A schematic diagram of an electric vehicle 11 having an embodiment of an electric machine 20 according to the invention with a valve 10 according to the invention is shown.

[0040] The valve 10 is designed or arranged here at the deepest point of the motor 20 or at the bottom 15 of the motor 20 . The valve is thus arranged at the point in the electric machine 20 where the greatest amount of condensed water 14 accumulates. Since the valve 10 is arranged at the bottom of the motor 20 , as much condensation water 14 as possible can be drained away when the valve 10 is open.

[0041] The valve 10 is designed electronically and is designed to be controllable. The electronic valve 10 is here arranged in an embodiment of the invention by control logic to be able to be switched or adjusted from the first position 12a to the second position 12b. In the first position 12a, the electronic valve 10 is arranged to seal off the electric motor 20 . In the second position 1...

Abstract

A valve 10 for an electric vehicle 11 for draining condensation from an electric motor 12, wherein the valve 10 is designed to be controllable electronically. Furthermore, the present disclosure relates to an electric motor 20 including at least one valve 10 as described above.

Description

technical field [0001] The invention relates to a valve for an electric vehicle for draining condensed water from an electric motor. Background technique [0002] Condensation in the electric machine can cause ISO failures in the stator of the electric machine or lead to a short circuit, whereby the electric vehicle can no longer move due to damage to the electric machine. [0003] It is known from the prior art that condensation water collects in relatively deep regions of electric machines. Furthermore, valves for draining condensed water are known from the prior art. [0004] An electric machine is thus known, for example, from document KR 101 598 040 B1, in which the rotor housing has a valve for draining condensation water. [0005] An electric motor is known from document CN 204 512 542 U, which has a non-return valve for removing condensation water. [0006] From document CH 155 891 A a method is known for removing condensation water in electric machines. The cond...
