Product Description:

The MDD093D-N-040-N2M-130GA2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with compatible digital drive controllers to generate precise rotary motion in automated machinery. The motor combines its mechanical interface, feedback system, and integrated holding brake to deliver controlled torque and speed while also helping an axis remain in position when power is removed. In closed-loop applications, commanded current from the inverter is converted into proportional shaft torque for packaging lines, material handling stations, and high-cycle assembly equipment. This arrangement supports accurate acceleration and repeatable stopping behavior during continuous machine operation.

The motor delivers a continuous standstill torque of 24.0 Nm, so it can hold or slowly move loads without overheating while current remains constant. It has a rated speed of 4000 rpm, which keeps back EMF, winding temperature, and mechanical balance within nominal operating conditions during production duty. Position data are returned through digital servo feedback, allowing the drive to correct deviations during each control cycle. A centering diameter of 130 mm keeps the stator aligned with the machine flange, and the output uses a plain shaft for direct coupling. Power and feedback leads exit on side A, which can simplify cable routing in compact machine layouts.

The blocked-rotor brake provides 22 Nm of holding torque, allowing vertical axes to remain stationary during emergency stops or power loss. The design uses motor length code D, which adds rotor and stator overlap for greater copper volume and more thermal mass during intermittent overloads. The output end is supplied with a shaft seal, which helps limit the entry of coolant mist or fine dust at the shaft. Standard dynamic balancing helps reduce vibration during operation, and the connector arrangement allows premolded cables to be attached in a straightforward way.
