Suited for most AC induction motors, the SKF Motor Encoder Unit is available in a range of sizes for shaft diameters from 15 to 45 mm, with a free cable end or connector that best fits your application.
The new model sensor bearings are compatible with its precedent model, for example the BMO-6206/064S2/UA108A can replace the BMO-6206/064S2/UA106A.
SKF motor encoder units use a compact and robust sensor that produces an incremental encoder signal. The sensor is accurate down to zero r/min. An integrated active circuit (requiring an external voltage supply) in the sensor body contains two Hall effect cells that produce an output signal consisting of two square waves.
The signals can be interpreted by motor controllers in different ways:
The two square waves are 90° out of phase with each other. This phase shift changes sign with the direction of rotation. The presence of two signals in quadrature enables a processing unit to multiply the number of angular position increments per revolution. For example, using a standard SKF sensor bearing with 64 pulses per revolution and a standard electronic interface that can detect the rising (Low/High) and falling (High/Low) times of each of the two signals, it is possible to obtain 256 electrical events per revolution, which translates to an angular resolution of 1,4°.
SKF motor encoder units provide accurate and reliable signals for effective motor control and are 100% tested for period accuracy, duty cycle and phase shift during manufacture.
The SKF Motor Encoder Unit is a compact, integrated unit consisting of:
