What are the implications of the resolver feedback in the Bosch Rexroth MDD021B-N-100-N2G-032MA0 motor for position accuracy and control loop tuning?

Resolver feedback provides analog rotor position signals that are robust to harsh environments and electrical noise, but require precise calibration and possibly complementary electronics to convert to digital form. It means the control loop must account for resolver’s non-linearity and may impose latency, so sampling rate and interpolation impact achievable position accuracy.

How does having 0.30 Nm continuous torque at standstill affect the motor’s ability to hold load without motion or drift?

At standstill with 0.30 Nm, the motor can resist moderate loads or torques that would otherwise move the load when stationary; but for heavier holding needs one would need a brake or a motor with higher standstill torque. Also, thermal limits matter: keeping the motor energized at standstill draws current that heats up windings, so continuous duty may require cooling or specifying temperature rise limits.

What trade-offs come with operating a synchronous motor at a nominal speed of 10,000 min⁻¹?

High nominal speed enables high dynamic response and high output power for its size, but increases centrifugal stresses on rotor, higher friction and bearing loads, and demands for precise balancing. It also pushes up losses (air-friction, windage) and may reduce lifetime if cooling or lubrication are marginal.

What does "standard balancing" imply in terms of vibration, noise, and mechanical lifespan?

Standard balancing ensures that the rotor is balanced to a baseline grade, so at rated speed vibrations are controlled, but may not be sufficient for extremely low-noise or precision applications (e.g. high-speed spindles or metrology). If your application is sensitive (e.g. optics, precision robots), you might need upgraded balancing (precision/trim balancing) to reduce run-out and mechanical stress.

How does omission of a blocking brake affect design in robotics or applications requiring load holding?

Without a blocking or holding brake, the motor cannot mechanically lock the load when power is off, so external braking, failsafe mechanical locks, or controlled power removal must be designed in. For safety or precision positioning under power loss, this is a critical consideration.
