Product Description:
The MDD090B-N-020-N2L-110PA0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts regulated three-phase current into accurate mechanical rotation for automated pick-and-place units, conveyors, and positioning tables. Direct coupling to Indramat power modules supports coordinated multi-axis motion in industrial cells. Its synchronous design supports repeatable starts, stops, and speed changes during cyclic machine operation. The 090 frame size matches medium-duty axes that require precise velocity control.
With a nominal speed of 2000 rpm, the rotor suits 50/60 Hz drive systems and allows moderate overspeed margins. At standstill, it delivers 7.2 Nm of continuous torque, supporting indexing tables without excess heat rise. Alignment to gearboxes or flanges is guided by the 110 mm centering diameter, which helps keep runout low. Power and encoder leads exit on Side A, and position data is returned through digital servo feedback to the drive. A sealed connector simplifies electrical connection without disturbing the mechanical fit. This arrangement helps the controller correct load-related deviations during acceleration and steady operation. The 090 frame balances a compact stator diameter with enough iron for thermal damping under rated load.
The rotor and shaft are matched through keyway machining, allowing positive torque transfer to pulleys or couplings. Internal components use standard balancing, so additional field correction is rarely required within the normal speed range. The motor is supplied without a blocking brake, which lowers inertia for rapid reversing, and applications that need static holding must rely on external clamps or drive torque. An oil-tight shaft seal is fitted, and the shaft is finished only on the drive end. The length code B construction keeps overall depth moderate for tight machine compartments. The single drive-end shaft layout also leaves the opposite end free of output hardware.
