SKF Sensor Bearing Units

In a washing machine it is important to know the rotational speed of the drum. This is to control the motor by closing the speed loop.

In a standard washing machine the speed is measured on the motor that moves the drum through a rubber belt. To obtain a more precise speed signal SKF has developed the sensor bearing unit.

The unit mounted on the drum has 2 main functions:

  • support the load 
  • measure the speed.
