Traction Motor Bearing Units (TMBU) with sensor capabilities
The sensorised TMBU concept not only helps achieve a lower life-cycle cost as a highly reliable, sealed and greased bearing units, it also offers several detection and measurement opportunities, including:
- absolute positioning detection for traction motor control devices
- detection of direction of rotation
- speed measurement for brake control systems
- temperature measurement to monitor reliability
The incremental sensor unit is integrated into the sealing system of the outer ring of the bearing unit. This design is very space-saving, especially in the axial direction compared with conventional sensor devices. SKF TMBUs offer:
- space saving design, fewer parts
- high resolution and accuracy
- robust and long life design
