The hollow shaft allows the rotary encoder to be directly coupled to the mating shaft. An additional rotor coupling is not required. The resulting high rigidity permits higher bandwidths in the control loop, reduces inaccuracy, and simplifies installation.
Block commutation signals
Along with TTL signals, the rotary encoders of this series also output U, V, and W block commutation signals for direct commutation control. These rotary encoders can therefore be used directly on most downstream electronics for motor control.
The stator coupling compensates for play between the motor and the rotary encoder, thereby reliably correcting inaccuracy. Even tilt and axial play can be compensated for. The stator coupling also facilitates easy mounting onto the plane surface.
The encoders of this series feature high ruggedness and reliability in a compact design, with an outer diameter of just 35 mm. Their small footprint makes them ideal for tight installation spaces.
