Product Description:

The MDD090B-N-030-N2L-110GB1 is a synchronous AC servo motor developed by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into precise shaft rotation for positioning tables, packaging axes, and other automated machinery. The unit operates in closed-loop systems where fast feedback and stable torque help maintain cycle accuracy on high-speed production lines. Its plain shaft and standardized housing support direct coupling to driven loads or integration with gearboxes, while the internal blocking brake helps hold position when power is removed.

The motor provides a continuous standstill torque of 7.2 Nm, which supports holding force at zero speed without excessive thermal stress. Under rated excitation, it reaches a nominal operating speed of 3000 rpm, allowing the connected drive to command a wide working range for positioning and speed control. A blocking brake supplies 6.5 Nm of holding torque to secure vertical or offset loads when the amplifier is disabled. Rotor position is reported through digital servo feedback (DSF), giving the controller accurate position data for closed-loop regulation. A centering diameter of 110 mm provides the mounting reference for flange installation and helps keep the motor aligned with the machine interface.

The motor uses size 090 with length code B, which indicates the frame geometry and stack length used for this model. All power and feedback connectors are oriented on Side B, which helps route cables away from the driven shaft side and can simplify installation in compact axis layouts. A factory-installed shaft seal helps protect the internal bearings from coolant spray and airborne contaminants during operation. Standard dynamic balancing supports smooth running at operating speed, and the shaft has a single plain output end without a secondary extension, which keeps the mechanical layout straightforward in tightly spaced multi-axis equipment.
