What are the trade-offs of a continuous standstill torque of ~0.33 Nm for robotics or semiconductor tooling?

At standstill this torque limits how large the static load or moment the motor can hold without slipping; in robotics it means the payload or lever arm must be sized so that the torque requirement stays below ~0.33 Nm. For semiconductor or pick-and-place use, gear reduction or mechanical advantage may be needed if drum loads or high inertia are involved to avoid stall.

How does the blocking (holding) brake with 1.0 Nm holding torque affect safety and power consumption when the motor is shut off?

The brake provides safety by physically preventing motion when power is removed; however it may draw standby current if it is an active brake, so designers must verify the brake’s coil spec and whether an external supply must stay energized. Also, thermal isolation or heat dissipation around the brake should be considered if frequent engages/disengages occur, to avoid overheating.

What are the implications of using resolver feedback rather than a digital encoder in closed-loop control at high rpm?

Resolvers offer better robustness against heat, vibration, dust and electromagnetic interference and survive harsher environments; however, the analog signals need a resolver-to-digital converter (RDC) whose bandwidth, latency, and signal-noise characteristics impose limits on control loop speed and precision. At high rpm, phase lag and excitation frequency constraints of the resolver and its converter must be accounted for to maintain stable speed and torque control.

How does nominal speed of 10,000 rpm impact bearing selection, cooling, and vibration issues?

High rpm demands high-speed rated bearings with minimal friction and good lubrication; unbalanced rotor or misaligned shaft connectors or mountings can excite vibration modes, so balancing is critical. Cooling (air or external) must be enough to dissipate I²R losses, windage, and frictional heating, since losses scale non-linearly with speed.

Considering product code “MDD025A-N-100-N2G-040FB1” by Bosch Rexroth, what should I check for correct mounting and shaft alignment?

You should check centering diameter (40 mm in this case), side (B-side) connector orientation, shaft type (plain shaft), and make sure the motor’s mounting surfaces are flat and within tolerance so that the plain shaft does not suffer misalignment; coupling or connector orientation (side B) must match the machine’s layout. Also verify that any connector clearance and cable routing avoid stress on the connector during vibration or movement.
