Product Description:

The MDD090C-N-020-N2M-130GR1 synchronous servo motor is manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it couples with Indramat drive modules to provide precise rotary motion in automated material handling, machining, and assembly stations. Its electromechanical design supports feedback-driven positioning so axes can accelerate, hold load, and reverse under closed-loop control.

With frame designation 090 and length code C, the rotor and stator dimensions place the unit in the mid-range of the series. At rated excitation, it reaches a nominal speed of 2000 rpm and delivers a continuous standstill torque of 10.4 Nm. Standard balancing keeps vibration within accepted limits, and the housing uses a standard unventilated enclosure for cabinet mounting. A centering shoulder of 130 mm simplifies alignment on the machine plate. All power and feedback leads exit on the right side because the terminal set uses a connector interface, which eases cable routing in compact cabinets. Position and velocity signals are returned through digital servo feedback, allowing the drive controller to close current and position loops without an external transducer.

The motor is delivered with a blocking brake that supplies 6.5 Nm of static holding torque when mains power is removed. Position reference is maintained by the integrated multi-turn absolute encoder, which stores rotor angle over multiple revolutions so homing cycles are not required after power returns. A plain shaft is provided on side A, and a shaft seal helps limit lubricant loss and block particle ingress. There is no side B shaft end, which shortens the assembly for compact axes. The service connectors align with existing cabinet wiring and support orderly cable routing inside the enclosure.
