Product Description:

The MDD090C-N-020-N2M-130GB1 is a synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded electrical power into controlled rotary motion for CNC axes, packaging equipment, and other automated machinery. This unit includes an integrated multi-turn absolute encoder, so the control system knows the rotor position immediately after power-up. That arrangement supports accurate startup behavior and reliable positioning when the axis must resume operation without a new reference move.

Its continuous torque at standstill reaches 10.4 Nm, allowing the axis to hold or move low-speed loads without overheating. The rotor can achieve a nominal speed of 2000 rpm, which suits machinery that runs within common servo operating ranges. Position and velocity data are returned through Digital servo feedback (DSF), enabling closed-loop control with 32-bit resolution. A blocking brake inside the end bell delivers a holding capability of 6.5 Nm, helping keep a vertical axis in place when power is removed. Power and encoder connectors are oriented toward side B, which can simplify cable routing where the rear of the motor faces the operator side of the machine. The centering flange has a diameter of 130 mm, helping the frame seat accurately on a gearbox or machine mount.

The motor includes a shaft seal to help keep coolant and dust away from the bearing system during washdown or oil-mist exposure. Motor size 090 places the unit in a compact frame that fits many servo installations without requiring an oversized mounting area. The length code C gives it a mid-range stack length, providing a practical balance between torque capability and installation depth. Standard housing construction and rotor balancing support smooth, low-vibration operation across the motor’s intended speed range.
