Product Description:

The MDD090B-N-020-N2L-130PA1 is a three-phase synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for operation with digital drive controllers, the unit converts commanded current into controlled mechanical motion for automated transfer lines, tool changers, and similar equipment. Its integral blocking brake secures the shaft when power is removed, and the standard housing supports cabinet or machine-frame mounting without additional covers, making the motor a compact actuator for general-purpose industrial automation.

At a nominal speed of 2000 rpm, the rotor reaches synchronous velocity while staying within the thermal limits of the standard housing. During a stationary hold, the electromagnetic system can deliver a continuous torque of 7.2 Nm, which is sufficient for supporting loads at standstill without overheating. For emergency stops or vertical axes, the mechanically applied brake supplies 6.5 Nm of static holding torque. Accurate alignment to adjoining gearboxes is facilitated by a centering diameter of 130 mm, which provides the pilot fit on the mounting face. Position data is transmitted through digital servo feedback (DSF), allowing the controller to close the speed and position loops with microsecond latency.

The motor uses a standard balancing grade, which helps minimize residual vibration in installations that specify ISO quality levels. Its frame is identified as size 090 with length code B, a combination that sets the active stack length and overall mass. Power and encoder leads exit on Side A, and quick engagement is provided by a single multi-pin Connector rather than screw terminals. A radial lip seal is fitted on the output shaft to retain lubricant, and the shaft terminates in a keyway profile suited for keyed couplings. Because the shaft end is only on side A, alignment of external mechanics is straightforward and axial sealing integrity is maintained.
