Experimental Design for Characterization of Force Transmissibility through Bearings in Electric Machines and Transmissions

Abstract: With the increasing stringent emissions legislation on ICEs, alongside requirements for enhanced fuel efficiency as key driving factors for many OEMs, there are many research activities supported by the automotive industry that focus on the development of hybrid and pure EVs. This change in direction from engine downsizing to the use of electric motors presents many new challenges concerning NVH performance, durability and component life. This paper presents the development of experimental methodology into the… Show more

“…The displacement of the bearing centre governs the conditions at the contact and was found experimentally using a high-speed bearing test rig, originally reported by Walker et al [23]. A 5 kW AC synchronous motor, capable of reaching up to 32 000 rpm was coupled to a steel shaft that is supported by two bearing brackets.…”
