Product Description:

The MDD090A-N-030-N2L-110GB2 is a servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts regulated electrical power from an inverter into rotary motion for positioning tasks in industrial automation. The unit relies on permanent-magnet excitation to deliver stable torque in compact machinery zones where accurate speed tracking and closed-loop feedback are required. This arrangement suits feed axes, indexing systems, and handling equipment that require repeatable motion under changing load conditions.

Its nominal rotor velocity reaches 3000 rpm, enabling direct coupling to machine elements without gear multiplication. At standstill, the motor can supply 3.7 Nm continuously, so a drive can hold moderate static loads without thermal overload. A blocking brake is integrated and can clamp the shaft with 11.0 Nm when power is removed. The motor has a size code of 090, which matches standard MDD mounting flanges. The built-in digital servo feedback (DSF) transmitter returns position and velocity data to the controller for high-resolution current loops. This feedback path allows the connected controller to monitor rotor state continuously during acceleration, deceleration, and low-speed holding. The motor has standard balancing and a standard housing, and motor length code A keeps overall depth minimal. The windings terminate on a connector on side B, which helps keep cable routing organized.

A centering shoulder of 110 mm aligns the front face with precision gearbox plates, and all power, brake, and feedback connections exit on side B, keeping the cable bundle clear of moving tooling. A fitted shaft seal protects internal bearings from coolant spray, and the plain shaft configuration transmits torque through friction couplings rather than keyed hubs. The absence of a secondary shaft end reduces overhang mass, and the connector-style termination keeps the rear connection area compact. This layout also leaves more room around the motor body when clearance behind the installation is limited.
