The R911258373 (MDD065A-N-040-N2L-095PB1) is a Bosch Rexroth MDD065A series digital AC servo motor engineered for applications requiring precise, high-frequency operation such as machine tools, textile, printing, packaging machinery, and robotic systems. This unit is a brushless, permanent magnet-excited synchronous motor utilizing electronic commutation and digital servo feedback (DSF) for accurate indirect position measurement. It delivers a continuous standstill torque of 0.8 Nm, incorporates a blocking brake with 3.0 Nm holding torque, and achieves a nominal speed of 4000 min⁻¹. The motor features a standard housing and balancing, a 95 mm centering diameter, a shaft with keyway per DIN 6885-1, shaft-sealing ring, and an IP65-rated enclosure. Operating conditions include ambient temperatures from 0 to 40°C and up to 95% relative humidity. The electrical connection is established via a connector oriented at Side B, and the shaft end is standard without a side B extension.

Frequently Asked Questions

How does the blocking brake on the MDD065A-N-040-N2L-095PB1 improve safety?

It mechanically locks the shaft when the drive is powered off, preventing unintended movement. This is critical in vertical or load-holding applications where drift could damage equipment or pose safety risks.

What practical impact does a shaft seal have in this motor?

The shaft seal protects against dust, oil, or moisture entering the housing. This extends service life and ensures reliable operation in industrial environments.

What does a keyway shaft offer compared to a smooth shaft?

A keyway allows secure coupling with pulleys, gears, or couplings. This prevents slippage under load, which is essential in torque-transmission applications.

How does the MDD065A-N-040-N2L-095PB1 handle continuous torque demands?

It is designed to maintain torque delivery without overheating at standstill. This makes it suitable for holding loads in place while the motor remains energized.

Why is the connection direction on side B relevant during setup?

Side B connection simplifies cable routing in specific machine layouts. It reduces cable bending stress and helps fit motors in compact installations.
