MDD090A-N-030-N2L-110GB0

For the Bosch Rexroth / Indramat MDD090A-N-030-N2L-110GB0, what are the mechanical bearings’ load limits and how should shaft loads be managed?

The motor is designed so that Side A bearing handles radial loads and Side B handles axial loads, with limits given in the project planning manual for the MDD series. Exceeding those limits (via heavy pulleys, long cantilevers, or misalignment) accelerates bearing wear or causes failure.

How does the motor centering diameter of 110 mm affect mounting and coupling alignment?

The centering diameter establishes how the motor is aligned on mating flanges or bearings; a precise 110 mm diameter enables repeatable and concentric mounting. Poor alignment at that interface can cause imbalance, vibration, and premature wear of bearings or the driven components.

What cooling and duty-cycle considerations should be taken into account for continuous operation at 3000 min⁻¹?

At 3000 rpm continuously, the motor will generate heat proportional to losses (electrical, frictional, iron losses), so adequate ventilation or surface cooling is required to stay within thermal limits. If the ambient temperature or duty cycle is harsh (frequent starts/stops, high torque near limit), derating or additional cooling (fans or airflow) may be necessary.

How does the absence of a blocking or holding brake (in the “without blocking brake” version) affect safety or process design?

Without a holding brake, the motor cannot resist external forces when unpowered – meaning loads may drift or unload under gravity or spring forces. Applications requiring holding position when power is cut must design in external brakes, mechanical locks, or select the version “with blocking brake.”

How does the motor’s standard balancing class (for size 090) influence vibrational performance in high-speed or precision setups?

This motor is balanced to “reduced” balance class (for MDD size 090), which limits vibration contributions from rotor imbalance under dynamic loads. For high-precision, high-speed, or long shafts / cables / mounted tooling, careful balancing, alignment, and vibration damping improve lifespan and performance.
