The Bosch Rexroth R911253368 (MDD093B-N-020-N2L-110PL2) is a servo motor designed for integration with digital drive controllers. This motor features a standard housing and shaft with keyway and seal, a centering diameter of 110 mm, motor size 093, and length code B. It delivers a maximum torque of 45.1 Nm and a continuous standstill torque of 14.5 Nm, supported by a maximum current of 76 A and a nominal speed of 2000 RPM. The thermal time constant is 50 minutes, and the motor operates within a 0 to +45 °C temperature range. It includes a digital servo feedback system, an IP65 protection rating, and a holding brake rated at 22 Nm. Inertia is specified at 29 x 10⁻⁴ kg·m². The connection is via left-side connector, and the product requires a clean, dust-free installation environment.

Frequently Asked Questions

How is the holding brake managed during e-stop or power loss?

The drive can clamp immediately, below 10 rpm, or after ~400 ms—selectable via parameters. It is a holding brake, not a service brake; add external safety measures if personnel protection is required.

What should be done if the motor’s brake has been idle in storage for years?

Reseat it and run the motor ~100 rpm, close the brake for ~60 seconds, then reconnect it to the drive. This restores proper friction conditions before returning to service.

Does adding a shaft seal change the environmental rating at the shaft?

Yes without a shaft seal the shaft area is IP50; with a shaft seal it is IP65. Plan for splash/dust exposure accordingly and observe ambient limits.

How should a keyed shaft be coupled to the load?

Use a hub keyed per DIN 6885 with proper fit and axial clamping to prevent fretting and backlash. Align carefully to protect bearings and preserve servo stiffness.

What does a nominal speed around 2000 min⁻¹ imply for sizing and gearing?

Ensure the drive can supply continuous current at low speeds and check S1/S6 curves when choosing ratios. This speed suits geared axes or direct indexing where torque at low speed is prioritized.
