The Bosch Rexroth servo motor MPN R911259138 (MDD093C-L-030-N2M-110GA2) is engineered with a surface-cooled housing and digital servo feedback featuring an integrated multiturn absolute encoder, which delivers system accuracy of ±0.5 angular minutes and position retention after power loss. The motor achieves a nominal speed of 3000 min⁻¹, with a standard plain shaft and shaft sealing ring to guard against fluid ingress. Its blocking brake provides 22 Nm holding torque, and the brushless, lifetime-lubricated bearing design enables maintenance-free operation. Key mechanical parameters include a 110 mm centering diameter, motor size 093, and motor length code C.

What is the practical benefit of the integrated multiturn absolute encoder in MDD093C-L-030-N2M-110GA2 motor ?

The integrated encoder in MDD093C-L-030-N2M-110GA2 motor provides the motor’s absolute position through power cycles, eliminating external homing. It simplifies system design and reduces cost for position recovery.

How does the 110 mm centering diameter improve coupling accuracy?

The centering diameter ensures precise alignment between motor and load to reduce eccentricity. It lowers mechanical stress and improves repeatability in multi-axis setups.

Why is a 22 Nm blocking brake included with this MDD093C-L-030-N2M-110GA2 motor?

The holding brake of MDD093C-L-030-N2M-110GA2 motor secures the shaft at standstill to prevent drift or backlash under load. It’s useful in vertical axes or safety hold-in-place during power loss.

In what industry is the MDD093C-L-030-N2M-110GA2 motor commonly used?

This motor is suitable for robotics, CNC machines, packaging automation, and precision handling systems. Because of its feedback and brake, it’s ideal for automated motion control.

How many revolutions can the multiturn memory retain after power loss?

The motor’s multiturn absolute encoder stores up to 4096 revolutions of position history. It preserves absolute angle across large motion cycles.
