Product Description:

The MDD090A-N-030-N2L-110GR2 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Within an automation cell, it works with digital drive controllers to convert commanded current into repeatable rotary motion for positioning, feed-axis, or spindle tasks. Its design suits applications that need a medium frame size and integrated feedback while remaining compatible with the MDD drive platform.

At standstill, the motor can deliver a continuous torque of 3.7 Nm, allowing small to medium loads to remain clamped without overheating. Once energized, it reaches a nominal speed of 3000 rpm, a rate matched to fast positioning cycles common in packaging and handling equipment. Position and velocity are returned to the drive through digital servo feedback, so the control loop can resolve rotor angle without incremental encoders. The motor uses a centering pilot of 110 mm for mechanical alignment, and the rotor is balanced to the standard grade to minimize residual vibration at rated speed. All power and signal conductors exit on the right side of the stator to simplify cable routing. The output interface uses a sealed plain shaft, and the shaft end is supplied only on side A. A standard housing and the short A length code keep overall mass and inertia low.

A blocking brake integrated at the stator rear supplies 11.0 Nm of holding torque, so vertical axes can maintain position when mains power is removed. The output shaft is protected by a shaft seal, which restricts lubricant loss and guards the internal bearings from fine dust or coolant spray. Electrical termination is completed through a multi-pin connector, allowing cable attachment without opening the housing. The frame code 090 is the external diameter class used across the MDD platform, which simplifies the selection of compatible gearheads and flange adapters.
