Product Description:

The MDD090B-N-020-N2L-130GL1 is a synchronous servo motor produced by Bosch Rexroth Indramat for use with digital drive controllers and belongs to the MDD Synchronous Motors series. As a drive component, it converts controlled current from an inverter into mechanical rotation that moves or positions machinery axes in automated lines. Integrated feedback supports closed-loop control, letting the drive regulate speed and torque precisely for tasks such as indexing tables, packaging machines, or gantry systems. This operating principle helps the motor maintain stable motion during repeated starts, stops, and load changes in automated equipment.

At standstill, the motor can deliver 7.2 Nm of continuous torque, allowing it to hold static loads without overheating when the controller maintains excitation. During motion, it is optimized for a nominal speed of 2000 rpm, so standard control loops can reach full rated velocity without field weakening. For emergency or power-off stops, the built-in blocking brake supplies 6.5 Nm of holding torque, mechanically locking the shaft once the controller releases current. Accurate position reporting comes from the integrated digital servo feedback (DSF) encoder, which sends motion data to the drive for closed-loop operation. Precise motor mounting is supported by a centering shoulder that measures 130 mm in diameter, helping keep the motor aligned with the machine flange. This combination of torque, speed capability, braking, and feedback supports positioning tasks that require repeatable response and controlled stopping behavior.

Electrical terminations use a keyed connector placed on the left side of the housing, so cable routing can follow cabinet layouts without crossing adjacent axes. A factory-installed shaft seal prevents lubricant migration along the plain shaft, which helps protect nearby mechanical components during operation. The seal arrangement also supports enclosed machine layouts where contamination control is important. Standard balancing, the 090 frame size, and the B length code help reduce vibration while fitting into compact actuator spaces. Housing and shaft-end configurations follow the standard arrangement for this motor type, which helps it match common MDD mounting and coupling layouts.
