MDD090C-N-020-N2L-110PR0

The Bosch Rexroth Indramat MDD090C-N-020-N2L-110PR0 servo motor is a high-performance member of the MDD Synchronous Motors series, engineered for precision motion control in digital drive systems. This rugged Digital AC Servo Motor utilizes a permanent-magnet rotor and a built-in encoder for commutation, rotor position, and speed feedback. The robust design delivers reliable continuous operation with a Continuous Torque at Standstill of 10.4 Nm and supports dynamic acceleration profiles at its Nominal Speed of 2000 min⁻¹. Engineered without a blocking brake, this model prioritizes compactness and efficiency in demanding automation environments. Designed for digital controllers, it offers seamless integration with drive electronics via a standardized connector interface.

The motor’s key dimensional and mechanical parameters include a Motor Size of 090 and a Motor Length Code C, resulting in a moderate footprint optimized for machine tool spindles and robotics. It features a precision-aligned Centering Diameter of 110 mm and a Standard (without side B) Shaft End driven by a keyed shaft per DIN 6885 sh.1, 8-68 Edition to ensure reliable torque transmission. The housing is configured in a Standard format, with Balancing: Standard to minimize vibration at high speeds. Sealing elements include a Shaft Seal to protect internal components against dust and debris. Connection is achieved through a right-hand Connector mounted on the housing’s Connection Direction: Right flange. Motor feedback is handled by Bosch Rexroth’s proprietary Digital Servo Feedback (DSF) system, eliminating the need for external encoders.

In operation, the MDD090C-N-020-N2L-110PR0 delivers consistent performance across varying load conditions. The integrated encoder supports high-resolution commutation, enabling precise speed regulation and position control with minimal latency. Continuous torque of 10.4 Nm at standstill ensures secure holding capability in indexing applications without supplemental brakes. Thermal stability is enhanced by the motor’s design, allowing uninterrupted operation at rated current levels. The keyed shaft interface prevents slippage under peak torque loads, and the standard balancing reduces resonant vibration, extending bearing life and maintaining accuracy.

System integration is straightforward thanks to compatibility with Bosch Rexroth Indramat digital drive controllers, including built-in diagnostics and real-time feedback loops. The motor’s compact MDD Series Digital AC Servo Motor architecture reduces cabinet space and simplifies wiring through standardized connectors. Target applications include CNC machine tools, industrial robots, packaging machinery, and automated assembly lines, where precise torque control, high dynamic response, and reliable digital communication are critical. This combination of specifications makes the MDD090C-N-020-N2L-110PR0 an ideal solution for advanced automation systems requiring tight control over speed and position.
