MDD093B-N-030-N5L-110GB0

Product Description:

Bosch Rexroth Indramat manufactured the MDD093B-N-030-N5L-110GB0. Bosch Rexroth’s MDD093B-N-030-N5L-110GB0 synchronous servo motor is designed for high-performance automation applications where torque, speed and control are required. The execution rate of motion sequences in industrial machinery is directly influenced by the motor’s nominal speed of 3000 min⁻¹, which is the rotational frequency the motor maintains under rated load. The motor’s contribution to system-level throughput is determined by this speed, especially in manufacturing lines where time synchronization is critical. From a control engineering perspective, torque production and thermal management must be balanced to maintain a constant nominal speed under changing load conditions. The motor has a constant stationary torque of 24.0 Nm in the middle of its static torque production. This is the steady state torque the motor can produce without exceeding heat thresholds when stationary.

It’s especially important in applications that need holding power, like indexing mechanisms, clamping units and pick-and-place robots. This torque production is thermally limited by the stator windings' ability to dissipate heat produced by resistive losses, so a design restriction is the winding resistance of 0.18 Ω at 20°C. By reducing I²R losses, this low resistance improves electrical efficiency and allows longer duty cycles under heavy load without heat accumulation that could damage the insulation. The motor’s peak current of 186.0 A is a critical transient value that defines the maximum torque that can be produced during sudden changes in load or velocity. The peak current defines the acceleration profiles and servo loop response by setting the top limit of torque production together with the torque constant of 0.58 Nm/A. The winding inductance of 2.1 mH controls the electrical time constant and how fast the current can change in response to controller signals.

The motor’s applications are also influenced by thermal and mechanical inertia. The motor’s angular acceleration is defined by a rotor moment of inertia of 58×10⁻⁴ kg·m², which also defines the energy needed to change rotational states. Together with the motor’s 28.0 kg mass, this inertia contributes to the mechanical resonance and stability of the dynamic system. A thermal time constant of 50 (45) minutes defines the thermal performance, the motor’s thermal delay and the power fluctuation response. The motor can run safely at ambient temperatures between 0°C and +45°C due to the insulation class F rating, which allows winding temperatures up to 155°C. An IP65 rated housing with a black primary coat (RAL 9005) provides external protection by radiative heat dissipation and environmental shielding. For both active operation and logistical handling, the MDD093B-N-030-N5L-110GB0 is designed to last with a transit and storage tolerance of -20°C to +80°C.
