The Bosch Rexroth R911253145 (MDD093C-N-020-R2L-110GA0) is a synchronous servo motor from the MDD series, featuring a rated speed of 2000 min⁻¹ and a 42x10⁻⁴ kg·m² rotor inertia. It uses a brushless design with high-quality, lifetime-lubricated bearings and implements digital servo feedback via an optical method for indirect position detection. The motor includes inbuilt data memory, supports natural convection and surface cooling, and utilizes rare earth and iron oxide permanent magnets in its rotor. The housing has an IP65 rating, a standard 110 mm centering diameter, and is coated for resistance to environmental effects. It incorporates a shaft seal, plain shaft (no blocking brake, no side B shaft end), and connection via connector on side A.

Why is balancing class R important for the MDD093C-N-020-R2L-110GA0 motor?

Balancing class R minimizes vibration and mechanical stress during high-speed operation. This leads to longer bearing life and consistent performance under continuous-duty conditions.

How does the shaft seal in the MDD093C-N-020-R2L-110GA0 protect the motor?

The shaft seal prevents contaminants like dust and moisture from entering the housing. This enhances the motor’s lifespan and ensures reliable operation in industrial environments.

What advantage does the standard housing provide in the MDD093C-N-020-R2L-110GA0?

The standard housing offers structural stability while maintaining efficient heat dissipation. It also ensures compatibility with common mounting configurations and mechanical interfaces.

How does the 2000 min⁻¹ nominal speed benefit the MDD093C-N-020-R2L-110GA0’s applications?

A nominal speed of 2000 min⁻¹ allows optimal torque delivery for dynamic motion tasks. It ensures consistent performance in systems requiring frequent acceleration and deceleration cycles.

Why is the 110 mm centering diameter significant in the MDD093C-N-020-R2L-110GA0 design?

The 110 mm centering diameter ensures accurate shaft alignment during installation. This reduces mechanical stress, minimizes vibration, and maintains precision in high-speed operations.
