The plain shaft offers flexibility for couplings or pulleys, while the shaft seal helps protect internal bearings and windings from dust, oil, or contaminants. However, the seal adds friction and must be properly installed and maintained to preserve its effectiveness.

DSF gives high-fidelity position/speed signals that improve closed-loop control accuracy, reduce lag, and allow tighter control of torque/speed transitions. It also demands compatible drive electronics and proper servo tuning to fully exploit the DSF’s performance.

Without a holding brake, the motor cannot prevent load drift or back-drive when unpowered; this may require external brakes or mechanical locks in vertical or otherwise gravity-affected axes. On the plus side, it simplifies the motor design and reduces cost, weight, and response delay associated with engaging/disengaging brakes.

Ensure the drive supports synchronous permanent magnet motors, can supply the required current for 10.4 Nm at standstill, matches the DSF protocol, and has adequate overcurrent / overload protection; also that connector polarity and pin assignments match Bosch Rexroth’s standard.

A good seal adds some drag and slight increase in rotational resistance especially at startup or low speeds, which may slightly delay acceleration or precision positioning. In many industrial motion applications this is negligible, but for very high dynamic performance (fast step changes) it might be limiting.
