Predictive maintenance of rail traction motors

The traction motor bogie has two axles each fitted with a 250kW traction motor driving the wheelset through a 4 15:1 ratio gearbox Initially a Schaeffler engineer took measurements horizontally on the traction motor housing at both the drive end and non-drive end positions by attaching an accelerometer with a magnetic base
