SKF Motor Encoder Unit - the new generation

Robust and reliable solution for your motor control

Combining bearing and sensor functionality in one unit, sensor bearings can be integrated in AC induction motors to allow precise speed and direction control. Thanks to their compact size, these sensor bearings can help to save space in electric motor designs. 

The new generation of SKF Motor Encoder Unit offers a much more robust and cost-effective solution. The sensor bearing is protected from the effects of power surges and electromagnetic fields to avoid electronic failures, resulting in a reduction of maintenance and warranty costs.

Built-in sensor protection

In addition to accurately detecting AC induction motor speed and direction, the new generation of SKF Motor Encoder Unit provides integrated protection for its electronic sensor. The unit features an electromagnetic interference (EMI) filter encapsulated in the sensor body to protect against inductive or capacitive power surges and electrostatic discharges. This shielded encapsulation results in an easy integration, as no extra space is needed outside the motor.
And thanks to the sensor body’s Faraday cage, this new generation unit is able to deliver accurate speed and direction data even in harsh electromagnetic environments.

Robust reliability and support

Combined, these integrated sensor protection features mean the new generation of SKF Motor Encoder Unit offers more reliable performance and longer service life than conventional sensor bearings. 

Available for 30 mm shaft diameter, this sensor bearing can be installed at either bearing position of AC induction motors.
