Product Description:

The MDD093B-N-020-N2L-130GL1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for integration with digital drive controllers, the unit converts regulated stator currents into precisely metered torque, allowing automated machines to position, index, or traverse loads under closed-loop control. The housing and balancing are supplied in the standard variant, so the motor fits the general mechanical footprint expected in modular industrial axes.

The motor can sustain 14.5 Nm of continuous torque at standstill, meaning it can hold that load indefinitely without exceeding thermal limits when the shaft is locked. During routine operation, its rated shaft velocity is 2000 rpm, which sets the electrical frequency and drive configuration for applications such as gantry traverses or tool spindles. Position information is returned through digital servo feedback (DSF), giving the controller high-resolution data for velocity and commutation loops. A 130 mm centering diameter registers the flange concentrically on the machine plate and helps keep radial runout low. All power, brake, and feedback plugs face the operator side because the unit uses a left connection direction, simplifying cable routing inside tight cabinets.

The integrated holding brake applies 11 Nm of static torque, so vertical or suspended axes remain secure when the drive is disabled. A plain shaft with no keyway minimizes backlash when clamped by coupling hubs, and the presence of a shaft seal helps keep lubricant inside adjacent gearboxes while stopping particulate ingress at the bearing seat. The motor size 093 uses pilot dimensions and bolt circles common to the MDD family. Motor length code B sets the stack depth, and the shaft is supplied without a side-B extension, allowing closer placement of neighboring equipment.
