Product Description:

The MDD041B-N-100-N2G-050MB0 is a synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for use alongside digital drive controllers, it converts precise current commands into high-speed rotary motion for compact pick-and-place heads, light indexing tables, and auxiliary machine axes where quick acceleration and repeatable positioning are required. Its compact frame supports responsive motion in tightly spaced equipment, and the synchronous design allows the paired drive to regulate speed and position smoothly during repetitive start-stop cycles.

At installation, the motor seats against a centering pilot of 50 mm, allowing accurate location on gearboxes or machine frames. Power and feedback cables exit on Side B, and the mating interface is a sealed connector that permits fast exchange without disturbing mounting alignment. At rated operation, the rotor can reach 10000 rpm, supporting high spindle or feeder duties, while delivering a continuous stall torque of 1.35 Nm for light loads. The standard dynamic balancing grade limits vibration transmitted to precision mechanisms and helps protect bearings at elevated speeds.

Closed-loop commutation is carried out by the integrated resolver feedback, which sends rotor angle data to the drive across the speed range. Mechanical coupling uses a shaft with a keyway, and the design is supplied without a blocking brake, so static loads must be restrained by the controller or external fixtures. The housing uses a standard aluminum frame and has no shaft seal, which suits clean, dry enclosures. Size code 041 and length code B keep overall mass low, and the single-ended shaft has no side-B extension. As a motor for digital drive controllers, the unit fits into Indramat modular drive racks where high-frequency current loops maintain commanded motion profiles.
