Product Description:

The MDD112B-F-040-N2L-130GA0 is a motor for digital drive controllers produced by Bosch Rexroth Indramat and sold within the MDD Synchronous Motors series. This B-length, size 112 unit converts drive commands into rotary motion for axes that require precise speed regulation in automated machinery. It uses standard balancing to limit vibration and features a plain shaft with a standard side B closure, making it suitable for belt-driven or direct-coupled loads in industrial plants.

Its continuous stall torque reaches 17.5 Nm, allowing the drive to hold loads without external gearing. A nominal speed of 4000 rpm aligns with high-speed packaging and material-handling tasks while keeping torque flat across the regulated range. The motor seats against a flange with a 130 mm centering diameter, a dimension that simplifies alignment with common mounting interfaces. Heat is removed through a housing designed for liquid cooling, so full torque is available during extended cycles without derating. Power and feedback conductors exit on side A, which reduces cable loops when the motor is installed close to a moving carriage. The connection follows the standard connector style, and the motor length code B keeps overall depth moderate for tight cabinet spaces.

The motor transmits position data through digital servo feedback (DSF), enabling the controller to execute tight velocity and position loops. It is supplied without a blocking brake, so lifting or vertical axes must be equipped with an external holding mechanism when power is removed. A fitted shaft seal protects the interior bearings from coolant splash or airborne particles and works with the plain shaft design to maintain low friction. Field wiring is completed through a single plug-in connector, which keeps the external connection straightforward.
