Product Description:

The MDD093B-N-040-N2L-130PR2 is a synchronous servo motor from Bosch Rexroth Indramat and is part of the MDD Synchronous Motors series for use with digital drive controllers. It delivers closed-loop rotary motion so automated axes can reach and maintain commanded positions under changing load conditions. When paired with a compatible controller, it supports responsive acceleration and repeatable positioning in servo-driven automation. The size 093 frame in a B-length housing fits standard Rexroth mounting patterns, and a factory-installed shaft seal helps keep lubricant in place while limiting the entry of fine particles into the bearing cavity. This arrangement suits continuous-duty operation in machining centers and material-handling systems.

The motor supplies a continuous standstill torque of 14.5 Nm, giving the drive enough holding force for static loads without external clamping. Under rated excitation it reaches a nominal speed of 4000 rpm, allowing rapid index moves in high-cycle positioning tasks. A blocking brake at the non-drive end provides 22 Nm of static torque to hold a vertical axis when power is removed. Rotor position is reported through Digital servo feedback (DSF), allowing the controller to regulate current, speed, and position with accurate feedback data. Mechanical power is transmitted through a keyway shaft, making the motor compatible with keyed hubs, timing-belt pulleys, and rigid couplings.

The centering pilot measures 130 mm in diameter, which helps align the flange accurately inside register bores and reduce radial runout at speed. The rotor and flange are trimmed to standard balance quality, which supports smooth operation without added field correction. Electrical power, brake, and feedback circuits enter through a single connector, reducing the number of separate cable entry points on the housing. All plugs face the right side of the housing, which helps cable routing stay orderly in tight cabinets or along machine frames. This layout can also reduce cable crowding near the motor end. The single-ended shaft leaves the rear of the motor free for other machine elements, while the shaft seal helps protect the internal bearings from coolant splash.
