The R911310289 (MHD112B-035-PP2-BN) is a Bosch Rexroth MHD112 synchronous servo motor designed for industrial machinery applications. This model features a keyed shaft with a shaft seal, a 192 mm flange, and a 130 mm centering diameter. It operates with a continuous current of 26–39 A, delivering 28–42 Nm of continuous torque and a characteristic speed of 3000 rpm. The winding inductance is 5.5 mH, and the voltage constant is 108.5 V/1000 rpm at 20°C. Equipped with an HSF absolute encoder and integrated digital servo feedback, it supports absolute position detection over more than 4096 revolutions. The motor includes a 32 Nm holding brake rated at 0.93 A, utilizes liquid cooling, and is suitable for ambient temperatures from 0 to 40°C.

Frequently Asked Questions

How does the MHD112B-035-PP2-BN maintain holding accuracy in vertical or suspended load systems?

Its 32.0 Nm holding brake secures the load under power-off conditions. This ensures reliable position retention in gravity-sensitive axes.

What ensures consistent torque delivery during zero-speed operations?

The motor delivers 28.0 Nm continuous torque at standstill for stable force output. This supports processes requiring full torque at zero RPM.

How does the shaft design contribute to mechanical integrity in high-torque drive trains?

A keyed shaft design provides rigid, backlash-resistant coupling. It prevents slippage under varying load transitions and rapid reversals.

Can high-resolution feedback be maintained in multi-axis synchronization scenarios?

The integrated encoder supports absolute position detection over 4096+ revolutions. This ensures precise coordination in real-time motion control systems.

Will mounting remain consistent under mechanical stress in automated assemblies?

Its 192 mm flange and 130 mm centering diameter allow precise alignment on standard servo mounts. This promotes structural stability in high-cycle systems.
