Product Description:

The MDD090B-N-040-N2L-130PL0 is a permanent-magnet synchronous servo motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is designed to work with compatible digital drive controllers and provide precisely regulated rotary motion for automated handling stations, indexers, and light machining axes in industrial automation. A brushless rotor, stator windings, and an internal position sensor allow the motor to produce closed-loop torque and velocity without mechanical commutation. This arrangement supports responsive motion control where repeatable speed and position behavior are required during changing load conditions.

Mounting precision is supported by a centering pilot of 130 mm, allowing the flange to seat squarely on machine frames with minimal runout. Power and feedback cables exit on the left side through a sealed connector, which helps cable routing where bend space is limited. At standstill, the motor can deliver 7.2 Nm of continuous torque, so static loads such as vertical slides can remain supported without excessive heating. During dynamic operation, the rotor can reach a nominal speed of 4000 rpm, which gives the axis useful headroom for rapid acceleration and high traverse rates. Position data is returned through digital servo feedback, allowing the controller to correct deviations during each control cycle and maintain stable motion when inertia changes.

The mechanical envelope follows size code 090, so the stator outer diameter, flange pattern, and mass match other 90-frame motors in the series. A keyway is machined into the shaft to transmit torque to pulleys or couplings. The front bearing region is protected with a shaft seal, which helps limit lubricant loss and reduce contaminant entry. The motor is built in the B-length version to provide a longer active stack, and it is balanced to the standard grade for smooth rotation. It is supplied without a blocking brake, so any holding function during power-off conditions must come from the drive or an external mechanical restraint.
