The Bosch Rexroth Indramat MDD093C-F-030-N2M-110GA2 servo motor from the MDD Synchronous Motors series offers robust digital motion control with liquid cooling for high-demand industrial applications. Featuring an integrated multiturn absolute encoder, this unit delivers precise position feedback and reliable synchronization under dynamic load conditions. The core design supports a nominal speed of 3000 min⁻¹ and continuous operation, ensuring consistent performance over extended cycles. A plain output shaft and blocking brake combination provide secure holding and mechanical simplicity, while the compact motor size minimizes installation footprint and maintenance requirements. This motor excels where accurate torque delivery and rapid response are critical.
Technical specifications include a continuous stall torque of 37.1 Nm and a stall current of 61.2 A, complemented by a peak current of 145 A for transient demands. The rotor’s moment of inertia is 0.0045 kg·m², with a winding inductance of 2.7 mH and winding resistance of 0.25 Ω measured at 20 °C. The motor’s mass is 22 kg without the holding brake and overall mass increases to 23.1 kg when the brake is attached. Cooling parameters specify a maximum system pressure of 3 bar, a pressure drop of 0.7 bar, and a maximum coolant flow rate of 1.4 l/min at a 10 °C rise. Electrical characteristics include an operating voltage of 24 V DC ±10%, a nominal current of 0.7 A, and a rated power loss of 970 W.
Operational features highlight a blocking brake with holding torque of 22 Nm, a release delay of 70 ms, and a clamp delay of 30 ms. The brake assembly adds 1.1 kg but is not intended as a service brake. Thermal management is governed by a thermal time constant of 25 minutes, allowing controlled heat dissipation during continuous operation. Ambient coolant temperature range spans 5 to 45 °C with coolant entry temperatures of 10 to 40 °C. Standard balancing and a centering diameter of 110 mm ensure low vibration and stable rotation in high-speed sequences.
Integration is streamlined through plug-in connectors on side A and compatibility with digital drive controllers for real-time diagnostics and parameterization. The plain shaft and standard shaft end simplify coupling to gearboxes, encoders, or load interfaces. Target applications include machine tools, packaging equipment, and automated assembly lines where precise synchronization, high torque density, and liquid-cooled thermal stability are required. The MDD093C-F-030-N2M-110GA2 motor delivers a balance of accuracy, power, and durability for demanding industrial motion control tasks.
