Product Description:

The MDD093D-N-020-N2L-110GR2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into precise rotary motion for positioning and velocity tasks in automated machinery. The unit has a plain shaft, no secondary shaft end, and an integrated blocking brake, making it suitable for single-ended load coupling where quick stopping and secure holding are required. It is intended for closed-loop axes that need repeatable motion and stable behavior during start, stop, and dwell periods. This arrangement also suits applications where the motor drives a coupling or gearbox from one side without using an auxiliary shaft extension.

At standstill the motor can supply a continuous torque of 24.0 Nm, giving static load support without overheating when current is held at the rated value. Its nominal operating speed is 2000 rpm, so the axis can run at a steady working speed during normal operation. Mounting uses a centering diameter of 110 mm, which sets the pilot fit in the machine frame and helps maintain alignment between the motor and the driven mechanics. Rotor position is relayed through Digital servo feedback (DSF), allowing the controller to close high-resolution loops for position, velocity, and torque. Power and feedback conductors exit on the right side, which can simplify cable routing on machines with right-side cable paths.

The integrated blocking brake generates 22 Nm of holding torque to secure vertical or inertial loads during power loss. A sealed circular connector provides a secure interface for the power and feedback harness while helping preserve the housing seal. Frame code 093 identifies the motor size, and the balanced rotor with standard grade balancing helps reduce vibration during acceleration. There is a shaft seal at the output end to help keep lubricant inside the gearbox interface and limit airborne contaminants from reaching the bearings. The sealed connection format also reduces exposed wiring transitions at the motor housing and supports clean cable entry in enclosed machine assemblies.
