The R911252969 (MDD090A-N-020-N2L-110GB0) is a Bosch Rexroth MDD digital AC servo motor, designed for precision and synchronism in applications such as grinding machinery. It operates with a nominal speed of 2000 min⁻¹ and delivers a continuous standstill torque of 3.7 Nm. The motor features a standard 110 mm centering diameter, standard housing optimized for natural convection and surface cooling, and a plain, sealed output shaft for effective torque transfer. Digital servo feedback (DSF) enables precise speed, position, and rotor state monitoring. Shaft seal and side B connector are included. The housing is coated black for weather resistance, supports efficient heat dissipation, and achieves IP65 protection.

Frequently Asked Questions

How does the IP 65 protection class contribute to the motor's longevity?

The IP 65 protection class ensures the motor is resistant to dust and water jets, significantly extending its longevity and reliability in industrial environments exposed to moisture or debris.

What operational conditions should be considered given the permissible ambient temperature range of 0 ... +45 °C?

The permissible ambient temperature range means the motor should be used in environments where temperatures are controlled within these limits, ensuring optimal performance and preventing overheating or thermal stress.

Why is the permissible storage and transport temperature range from -20 ... +80 °C important?

The wide storage and transport temperature range ensures the motor can withstand varying environmental conditions without damage, maintaining its integrity during shipping or temporary storage.

Would the 1000-meter maximum installation elevation limit MDD090A-N-020-N2L-110GB0 motor's performance at high altitudes?

Yes, at higher altitudes, air density decreases, reducing cooling efficiency and potentially causing the motor to overheat if used in environments above the 1000-meter limit without additional cooling measures.

How does the black prime coat (RAL 9005) impact the motor's resistance to wear?

The black prime coat (RAL 9005) provides an additional layer of protection against wear and environmental factors such as UV exposure and abrasion, enhancing the motor's durability over time.
