The R911258112 (MDD093B-N-060-N2L-110GB0) is a Bosch Rexroth digital AC servo motor from the MDD series, designed for machine tools, robotics, and textile machinery. It features digital servo feedback for indirect position monitoring and an integrated encoder with internal memory to store motor type and control loop parameters. The optical encoder provides a precision of ±0.5 angular minutes. This motor supports a nominal speed of 6000 min⁻¹ and a maximum torque output of 45.1 Nm. It features a plain output shaft with a sealing ring, a housing rated to IP65, and a thermal sensor integrated into the stator windings for overload protection. The unit operates within an ambient temperature range of 0 to 45°C, offers a centering diameter of 110 mm, a continuous torque at standstill of 14.5 Nm, and uses a side B connector for electrical connections. The shaft seal and standard housing enhance environmental protection.

Frequently Asked Questions

What continuous and peak torque levels define the MDD093B-N-060-N2L-110GB0 motor?

The MDD093B-N-060-N2L-110GB0 motor produces around 17.5 Nm continuous torque and a 52 Nm peak torque limit. These parameters enable efficient motion under repetitive acceleration and deceleration cycles.

How do the electrical parameters influence its energy profile?

The combination of moderate winding resistance and optimized inductance enhances current control and power balance. This design minimizes electrical losses and supports smooth torque transitions.

What are the implications of its rated 6000 rpm speed?

A rated speed of 6000 rpm allows responsive motion in compact servo assemblies. It provides high-cycle repeatability suitable for precision machining and robotic systems.

How does rotor inertia affect servo tuning performance?

The rotor’s inertia value near 3.0 × 10⁻³ kgm² supports balanced motion across load variations. This improves command response without inducing excessive overshoot in position control.

What thermal properties characterize the MDD093B-N-060-N2L-110GB0 motor?

The MDD093B-N-060-N2L-110GB0 motor includes a thermal time constant of about 50 minutes under standard cooling. This feature ensures gradual heat accumulation during sustained operational cycles.
