A 40 mm centering diameter ensures compatibility with standard mounting hubs and ensures precise concentricity when mounted; misalignment beyond tolerances can cause vibration, bearing wear and loss of positional precision, especially at high speed.

Although the spec sheet gives 0.33 Nm continuous at standstill, during short peaks or overload situations the motor can deliver significantly higher torque (for acceleration or transient load), limited by thermal capacity and drive current headroom; careful selection of the drive, cooling, and duty-cycle is necessary to avoid overheating.

The brake coil requires its own control circuit (often DC voltage supply) to release the brake; when power is off, the brake engages, so you should ensure proper wiring, consider response time, and avoid leaving the brake coil energized for excessive durations to limit heating.

Plain shafts simplify machining and reduce complexity, but require precision clamping or coupling to transmit torque; keyways/splines give more positive torque transmission and anti-slip, but introduce stress concentrations and possibly reduce fatigue life unless carefully designed.

In robotics/medical use, one must account for low backlash, noise, and precise motion control: ensure the drive’s resolver conversion latency is acceptable, that the holding brake does not introduce torque perturbations when releasing, and that thermal design (cooling, duty cycle) is sufficient to avoid drift or overheating in tight mounting or sterilizable enclosures.
