Product Description:

Bosch Rexroth Indramat supplies the MDD090A-N-030-N2M-110GL1 as part of the MDD Synchronous Motors series. It is a motor for digital drive controllers that converts drive commands into rotary motion for automated axes. The unit belongs to motor size 090 with the short A-length, fits into a standard housing, and includes an integrated multi-turn absolute encoder for position tracking across power cycles. A built-in blocking brake provides passive holding, while the shaft end is the standard single-sided version. These features support precise stops, starts, and coordinated moves in packaging lines, material-handling gantries, and other closed-loop systems.

The motor develops a continuous standstill torque of 3.7 Nm, giving stable force for static loads until commanded motion begins. During operation, it can reach a nominal speed of 3000 rpm, matching common inverter outputs used in fast cyclic applications. The blocking brake maintains position with a holding torque of 6.5 Nm, preventing back-driving when power is removed. Mounting is centered on a 110 mm pilot diameter that aligns the case accurately on the machine interface. All power and feedback conductors exit through a connection on the left side, and a keyed circular connector simplifies cable routing. Velocity and position data return to the controller through digital servo feedback, supporting high-resolution closed-loop regulation.

A standard balancing grade limits vibration at rated speed, which helps protect bearings and reduce transmitted noise. The presence of a shaft seal blocks coolant or dust from entering the front bearing zone, supporting use in splash or fine-particle environments. A plain shaft geometry eases coupling to precision clamping hubs. The absence of a side-B extension also helps the motor fit into tight machine frames without extra clearance at the rear.
