MDD090C-N-030-N2K-110PB1
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD090C-N-030-N2K-110PB1 motor belongs to the MDD Synchronous Motors series and delivers a robust solution for industrial automation requiring precise speed and torque control. This synchronous motor provides a nominal speed of 3000 min⁻¹ and offers a continuous torque at standstill of 10.4 Nm, ensuring reliable performance under load. With a peak current rating of 117.8 A and a torque constant of 0.53 Nm/A, the MDD090C-N-030-N2K-110PB1 accommodates dynamic acceleration profiles and demanding torque requirements. The design features a cylindrical steel shaft with keyway and a square flange with a 110 mm centering diameter, enabling straightforward mechanical integration. Electrical interfaces include a top-mounted circular multi-pin power connector and a gold-plated multi-pin encoder connector, both with threaded locking mechanisms for secure signal transmission.
The technical specifications of the MDD090C-N-030-N2K-110PB1 define its operational envelope clearly. It supports natural convection current of 19.5 A and surface cooling current of 30 A, delivering up to 16.00 Nm continuous torque when surface-cooled. The rotor exhibits a moment of inertia of 53×10⁻⁴ kg·m² and a theoretical maximum torque of 56.3 Nm, enabling high dynamic response. Insulation is rated Class F, and the motor incorporates a shaft seal for extended service life. The thermal time constant of 60 min (45 min at rated load) informs thermal management strategies, while permissible storage and transport temperatures range from –20°C to +80°C.
Operationally, the motor’s integrated absolute encoder provides high-resolution feedback for closed-loop motion control. An IP65-rated housing protects against dust and water ingress, and the brushless design eliminates the need for periodic maintenance. A built-in electromagnetic holding brake operates at 24 V DC with 6.5 Nm holding torque, drawing 0.5 A with ±10% tolerance, to secure the load during power interruptions. At a mass of 24 kg, the unit balances structural rigidity with manageable weight for handling and installation. Natural convection and surface cooling options offer flexible thermal dissipation under varying duty cycles.
System integration is simplified by compatibility with Bosch Rexroth Indramat digital drive controllers, enabling seamless commissioning and real-time diagnostics. The flange dimensions, 110 mm centering diameter, and standard shaft end dimensions facilitate interchange with existing motor mounts. Target applications include precise positioning systems, robotic actuators, CNC machining centers, and other industrial automation equipment where reliability, high torque density, and environmental robustness are critical. The MDD090C-N-030-N2K-110PB1 motor’s combination of performance, protection, and feedback capability underlines its suitability for demanding manufacturing environments.
