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 continuously measure speed and the direction of rotation.
SKF motor encoder units (fig. 1) are compact and ready-to-mount units that combine active sensor technology with an SKF Explorer deep groove ball bearing. These units, which can be mounted at either bearing position in an AC motor, are only 6,2 mm wider than the corresponding standard deep groove ball bearing (fig. 2). SKF motor encoder units can provide a signal resolution ranging from 32 to 80 digital pulses per revolution. They are available for shaft diameters ranging from 15 to 45 mm.
