Product Description:
The MDD090A-N-020-N2L-130PR1 synchronous servo motor is produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it serves as a torque and speed actuator in industrial automation where closed-loop regulation is required. Its synchronous design supports responsive acceleration and accurate speed regulation when paired with a compatible drive. The size 090 frame allows the unit to fit medium-power axes, and its standard mechanical housing integrates easily with cabinet-mounted inverters that require precise position feedback.
This model develops a continuous standstill torque of 3.7 Nm, meaning the rotor can hold that load continuously without exceeding its thermal limit. During routine motion cycles, the shaft reaches a nominal speed of 2000 rpm, a value matched to drive parameters for stable velocity control. Accurate mechanical centering is supported by a 130 mm pilot diameter, helping maintain shaft alignment inside geared or belt-driven assemblies. Wiring is simplified because the power and feedback plugs are oriented to the right side and use a connector interface that helps prevent incorrect mating. Command and feedback loops rely on digital servo feedback, so the drive receives position information for closed-loop operation without external sensors. Standard dynamic balancing limits residual vibration at rated speed and supports smooth running during continuous duty.
A blocking brake is factory installed and supplies 6.5 Nm of static torque, allowing vertical or suspended loads to remain fixed when the drive is de-energized. This is useful on vertical axes where load movement must be limited after power removal. The shaft uses a keyway profile for straightforward coupling to pulleys or gear hubs, and an oil-resistant seal helps protect the internal bearings from coolant splash. Because the shaft end is only on side A, the rear of the motor remains available for cable routing in tight machine layouts. The motor length code is A, which is the shortest housing in this frame size.
