Product Description:

The Bosch Rexroth Indramat MDD090C-N-020-N2M-110GB2 is a synchronous AC motor in the MDD Synchronous Motors series. Intended for use with digital drive controllers, it covers medium-frame applications through its 090 frame size and C length code. A standard housing and standard dynamic balancing allow direct machine mounting without added vibration measures. The output shaft includes a shaft seal, and the single-connector arrangement suits compact automation axes exposed to common factory-floor contaminants.

Mechanical and electrical ratings describe how the motor behaves during closed-loop operation. At standstill, it can deliver a continuous torque of 10.4 Nm, a value used to size couplings and gear stages that must hold load without motion. Under rated drive excitation, the rotor reaches a nominal speed of 2000 rpm, giving a practical balance between positional resolution and throughput. The power and feedback leads exit on Side B of the stator, and the electrical interface uses a keyed connector for secure cable attachment. Precise mechanical alignment is supported by a centering pilot dimension of 110 mm. Rotor position data comes from an integrated multi-turn absolute encoder, allowing the controller to track multiple revolutions without battery backup.

Dynamic arrest is handled by the integrated blocking brake, rated for 11.0 Nm of holding torque, so vertical axes can remain fixed when power is removed. Position and speed loops are closed through the motor’s digital servo feedback (DSF) channel, which relays high-resolution encoder data directly to the drive. The motor uses a plain shaft without a secondary side-B extension, which simplifies coupling to bellows or clamp hubs. The installed shaft seal also helps keep lubricant inside the machine enclosure while excluding splash water.
