Motor encoder units

Monitoring the status of rotating components accurately is essential for many applications. This is particularly true for AC motors that require encoders to measure the speed and the direction of rotation continuously.
SKF motor encoder units (fig. 1) combine active sensor technology with an SKF Explorer deep groove ball bearing and are:
  • able to provide a signal resolution ranging from 32 to 80 digital pulses per revolution
  • compact (only 6,2 mm wider than the corresponding standard deep groove ball bearing (fig. 2))
  • ready-to-mount and can be mounted at either bearing position in an AC motor
  • available for shaft diameters ranging from 15 to 45 mm
