Product Description:

The MDD093B-N-020-N2L-110PL2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts electrical commands from a Rexroth drive into controlled mechanical rotation for positioning, conveying, or machining axes in industrial automation cells. Its permanent-magnet rotor and stator windings are optimized for closed-loop operation, making the unit suitable for applications that demand repeatable torque output and precise speed regulation. Its design also supports repeatable response during frequent starts, stops, and speed changes on automated axes that depend on stable closed-loop behavior.

When rated current is applied, the motor can deliver a continuous standstill torque of 14.5 Nm, allowing stationary holding or slow-speed moves without overheating. The nominal mechanical speed reaches 2000 rpm, which is the synchronous speed the rotor can maintain under continuous duty. Integrated braking hardware supplies 22 Nm of holding brake torque, so vertical loads remain secured during power loss. Position and velocity loops are closed through digital servo feedback (DSF), which transmits high-resolution rotor data to the controller for tight motion control. A factory-installed shaft seal helps keep lubricant in place and blocks airborne contaminants from entering the bearing cavity.

A centering diameter of 110 mm aligns the front face to gearboxes or flanges with repeatable concentricity. Power and encoder connectors are oriented to the left side, which can simplify cable routing along gantry beams that travel to the right. The motor body uses length code B, providing a balanced compromise between inertia and penetration depth, while frame size 093 matches the bolt pattern common to other MDD units. Standard dynamic balancing minimizes vibration in high-cycle duty. The housing is supplied in the standard unventilated form, the keyway shaft end eases coupling to hub clutches, and the design omits a secondary shaft extension to reduce envelope width.
