Specification

1. An electric machine (120) for a vehicle (100), said electric machine (120)
comprising:
a shaft (315) disposed substantially in a lateral direction (RH-LH) of said vehicle (100), said shaft (315) fixedly supports a stationary member (305) and said shaft (315) rotatably supports a rotating member (310), wherein
a cable assembly (230) extends outward from a cable path (316) defined by said shaft (315), and an interfacing assembly (235), disposed at an opening portion (318) of said shaft (315), securely seals said opening portion (318) and said interfacing assembly (235) configured to route said cable assembly (230) therethrough.
2. The electric machine (120) as claimed in claim 1, wherein said interfacing assembly (235) includes a housing member (240) covering said opening portion (318) and annularly enclosing at least a portion of said shaft (315) at said opening portion (318), and said housing member (240) includes a first routing member (242) having an aperture portion (244) aligning with said opening portion (318).
3. The electric machine (120) as claimed in claim 1 or 2, wherein said interfacing assembly (235) includes a cable-guide (250), said cable-guide (250) includes an abutting portion (252) that is capable of being received by said housing member (240), and said cable-guide (250) capable of securely guiding said cable assembly (230) therethrough.
4. The electric machine (120) as claimed in claim 1 or claim 3, wherein said interfacing assembly (235) includes a sealing member (245), said sealing member (245) capable of securing said cable-guide (250) to said housing member (240), and said cable assembly (230) being routed through said shaft (315) and through said cable-guide (250) of said interfacing assembly (235).
5. The electric machine (120) as claimed in claim 4, wherein said abutting portion (252) of said cable-guide (250), said first routing member (245), and said opening portion (318) have a substantially common axis (X-X').

6. The electric machine (12 0) as claimed in claim 1, wherein said opening portion (318) having any known geometric profile includes an oval profile, and said interfacing assembly (235) substantially covers said opening portion (235) thereby restricting entry of any foreign particles including water, dust, or the like.
7. The electric machine (120) as claimed in claim 1 or 4, wherein the cable assembly (230) is secured by an elastic guard member (255) capable of annularly covering at least a circumference of the cable assembly (230), and said sealing member (245) includes a hook member (247) capable of holding the elastic guard member (255) in a desired position.
8. The electric machine (120) as claimed in claim 1, wherein said electric machine (120) is mounted to a structural member (135) of said vehicle (100), and said structural member (135) is secured to said vehicle (100) by at least one of fixed or swingable mounting.
9. The electric machine (120) as claimed in claim 1 or 2, wherein said first routing member (242) receives an abutting portion (252) provided at an end portion of the tubular portion (251) and the abutting portion (252) is sandwiched between the first routing member (242) and the sealing member (245).
10. An interfacing assembly (235), said interfacing assembly (235) comprising:
a housing member (240) capable of covering an opening portion (318), said housing member (240) includes at least one passage (242) to enable routing of a cable assembly (230) therethrough;
a sealing member (245) capable of being secured to said housing member (240); and
a cable-guide (250) providing a secure contiguous path from said opening portion (318) therethrough.
11. A housing member (240) for an electric machine (120), said housing member
(240) capable of covering an opening portion (318) of a shaft (315) of said electric
machine (315), said housing member (240) comprising:
a cylindrical base (241); and a first routing portion (242),

said cylindrical base (241) is capable of covering said opening portion (318) of said shaft (315), and said first routing portion (242) includes an aperture portion (244) aligning with said opening portion (318).
12. A method of assembling an interfacing assembly (235) to a shaft (315) of an
electric machine (120), said method comprising the steps of:
inserting a housing member (240) on to the shaft (315) whereby the housing member (240) covers an opening portion (318) of said shaft (315);
securing a cable-guide (250) to said housing member (240) whereby a cable assembly (230) can be routed from the shaft (315) through the housing member (240) and through the cable-guide (250).
13. The method of assembling an interfacing assembly (235) as claimed in claim 12, wherein securing said cable-guide (250) includes fastening a sealing member (245) to the housing (240).
14. The method of assembling an interfacing assembly (235) as claimed in claim 12 further comprising the step of aligning a first routing member (242) with an aperture portion (244) that substantially aligns with the opening portion (318) of said shaft (315).
