Product Description:

The MDD090C-N-020-N2L-110GL2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts electrical command signals into mechanical rotation. This supports positioning and velocity control on automated machinery and handling systems. Its synchronous design allows the drive to regulate torque and speed with the closed-loop response required for repeatable axis movement. The motor is suited to machinery that requires controlled starts, stops, and steady running under varying load.

This model provides a continuous standstill torque of 10.4 Nm, allowing it to hold loads without overheating when the rotor is locked. During motion, it reaches a nominal speed of 2000 rpm, which is the rated operating speed for the motor. A blocking brake is fitted, and its braking torque is 11.0 Nm, supplying passive load-holding capability whenever the power stage is disabled. The motor has a centering diameter of 110 mm for concentric mounting, and it uses a left-side connection orientation that places both power and encoder connectors on the left side of the shaft. This layout keeps cable routing consistent and the plug-type connectors simplify installation. Standard housing and size code 090 set the external frame envelope, while length code C sets the stack height inside the stator.

The feedback system is digital servo feedback, enabling high-resolution position loops inside the controller. Rotor mass distribution uses standard balancing, so no special balance correction is required for normal operation at rated speed. A shaft seal helps protect the internal bearings from contamination, and the motor uses a plain shaft in a standard single-ended configuration with no extension on side B. Because the shaft is plain rather than keyed, torque is typically transferred through a matching hub or clamping element. The standard shaft end and connector-based wiring support direct integration with gearboxes or belt pulleys. The integrated brake and feedback system help keep the axis stationary when power is removed and support accurate homing after power is restored.
